This frustrates me too, if something is "opt-in", that means by default you're not included and can choose to be included. If something is "opt-out", that means you're included and can choose not to be.
But then it gets used to describe the reverse, and we have to add words to clarify.
I once saw a post here with a correctly described opt-in telemetry before, and the top comment here was attacking them for the reverse, thinking it was including them by default, so there's little winning, it's one of those words that has just come to mean it's opposite.
Never miss opting in to newsletters again with NewsAI! NewsAI automatically opts you in to thousands of newsletters and marketing campaigns around the world in an instant!
Isn't it kind of like mandatory tip? If you haven't given it voluntarily, i.e .its automatically opted-in and you maybe can't even not give it. its the same.
Many restaurants have the audacity to add a 20% (or whatever percentage) "service fee" that isn't considered tip. It even says something like "we use this to pay our staff competitive wages and health insurance." You can't opt out. It's just part of the bill. Then they have the gall to ask for a tip on top of that.
I've taken to a) leaving a negative Google or yelp review for such establishments and b) never coming back. This is a practice that needs to die.
I've never had the pleasure of encountering that situation.
But at what point do we call a spade a spade and say it's just them secretly inflating their prices? "everything is a penny but we charge a 1000000% service charge"
I used to wait tables once upon a time and it was standard practice to add a fixed service charge for any large party in lieu of a tip. Have you really never encountered that?
I've encountered large party service charges and that makes sense because it usually requires staff to do stuff they wouldn't normally do for smaller parties.
I'm talking about restaurants that just add service charge to everyone.
I think the lesson from the airline industry is that while consumers will get angry about surcharges, pricing transparency is what really gets punished in the marketplace. There are enough consumers who will always buy the deceptively priced item that it's suicidal to tell the truth (absent government regulation forcing the issue for all purveyors).
There are a fair number of well-meaning restaurateurs who have tried no-tip policies for ethical reasons. But the mass marketplace has not changed.
Kinda reminds me of when Burger King had a 1/3 lb burger and a 1/4 lb burger and more people bought the 1/4 lb because they thought it was more burger than the (rightfully) more expensive 1/3 lb burger.
Opt-in by default means it is either mandatory (if you can‘t disable it) or it‘s opt-out (if you can)
Opt-In by default is BS to make it sound less invasive
That is slightly different though. The government says you must pay taxes, mandatory as you said.
PostHog here is saying they will train on your data but opting out is allowed. For the taxes analogy to work, PostHoh would not offer the opt-out option at all and you'd be doing something like hacking their system to filter your data out on their end.
You were given the option to option in, by default. Clearly it makes sense, optioned out by default only happens when someone loses money on the option in default instead.
The internet really stinks. The 1999 teenager in me somewhere is really bummed.
PostHog was a system we set up once, generally don't think about, and review from time to time, providing some occasional value. It was mostly harmless to leave around.
But it's apparently yet one more thing we have to be actively suspicious of as it defaults towards an intolerable state. So it's easier to just rip it out of the system and move on.
Most companies would bury this change in a deceptively boring T&Cs update, but we value transparency, so here's what you need to know in an internet-friendly numbered list:
Users on our EU cloud instance are opted out by default
So too users with agreements that prevent training (e.g. BAA, MSA, or similar)
All other users on our US cloud instance are opted in by default
We will anonymize all data before it's used for training
We will only use data that already exists in your PostHog instance
We will do all the model training ourselves, which means...
We won't sell or send your data to third-party model providers
You can opt out at any time via your org settings in PostHog (admin access required)
Training won't start until June 29, so there's plenty of time to decide
> All other users on our US cloud instance are opted in by default
Cool, cool. Glad to see that you are the arbiter of what your users have "opted" to do, and their input isn't required.
While we're at it, I'm going to "volunteer" your time to rebuild my patio this weekend. You don't need to worry about volunteering, I've done it for you.
If you send a postcard by Friday 5:00 PM, you can opt out of helping me with my patio. This is a one time offer; if you don’t, you have to help me every weekend for forever.
If "we will opt everyone in because otherwise we won't get enough data because we know users won't opt in" is your business model, maybe it's time for a rethink.
I'd recommend at least doing a short spike to see if you can build your own in some way. We did that for the purpose of experimentation and now we've built our own metrics platform that we completely own.
I sincerely hope this never comes to pass, but you or your loved ones may someday find themselves in the position of wishing more people were opted in for organ donation.
The same cannot be said for some random corporation training AI models off your data to make a buck or two.
I think it might be better to get rid of the organ *donation* system entirely.
Organ transplant surgery costs hundreds of thousands of dollars, yet donors get zilch, which is completely unfair when everyone else in the value chain gets paid.
If instead it was "allow my organs to be sold for my estate" I think the supply of organs would greatly increase, which would be win/win.
there are a number of problems with people selling their organs for profit, it's a perverse incentive — the people in the chain who otherwise get paid don't get paid for the organs, they get paid for the labor of doing their jobs
Off topic but I'm curious what's evil about that article. Bizarre, sure, but evil? They took a brain (an organ) from a dead person who had previously given consent to use their organs for that purpose.
I think most people, and definitely myself, when they sign up to be an organ donor, they think of the liver, kidney, and heart. Things that will help other people.
Not the brain, the center of conscience, being kept in some sort of horror-movie half-alive state. I do not think we understand consciousness enough to rule out what those brains are experiencing.
That's fair. Personally I wouldn't mind, but when you put it that way it makes sense people would be wary. Kind of reminds me of the series Pantheon, which is amazing but also kinda disturbing for similar reasons.
There is no such thing as opt in by default - and burning that amount of customer goodwill because you want something instead of say, giving a discount to people who are willing to do it is a choice for people who have a lot more market share and their customers would have more trouble leaving.
> Most companies would bury this change in a deceptively boring T&Cs update, but we value transparency, so here's what you need to know in an internet-friendly numbered list:
This feels like a really bad defense. It’s great you provide transparency but I don’t want my analytics system writing my code. There are already so many other first movers that are better that I would rather connect to your analytics.
> We will anonymize all data before it's used for training
Anonymize by what definition? GDPR? Do note that this very high bar.
> All other users on our US cloud instance are opted in by default
Including end users in the EU? You should remember that you are obtained the personal data directly from data subject meaning Article 13 obligations apply. Article 13 omissions cannot be cured retroactively. Can you show all of your customers have provided sufficient Article 13 notice to cover this processing?
And do note that you are almost definitely within the scope of 3(2)(b).
Hey man, respectfully, opt-in by default is not opt-in. That's opt-out, and it's scummy.
I feel like you either know that already, or should, but either way I won't be using your product anymore. Just pulled it out of the projects I'm personally in charge of and in the future I'm going to recommend against using it both internally and for clients.
There is definitely some confusion on the EU part. I am a European citizen, but some of my activity data on some of the sites I host is logged in US Posthog, which means Posthog is subject to the GDPR, even if the data is US hosted!
I think it would be better if there was an EU browser that provided a warning if accessing sites outside of the EU. If an origin site is in the EU then it could be subject to EU regulations.
> Users on our EU cloud instance are opted out by default
> All other users on our US cloud instance are opted in by default
Perfectly demonstrating that we need regulation to protect the general public, most companies will not do the right thing but the thing that benefits them first and foremost.
I don't want to support a company that's going to do everything they can possibly legally get away with, I want to support companies that do the right thing where they can.
What concrete difference is being made here? If a site is hosted in the US but accessible by EU citizens AND using a PostHog US server isn't the data still being used for training?
Legitimate question, I am not trying to prove a point.
Not really, it's slimy because it should be obvious that it's the morally wrong thing to do. There's no tangible benefit to the users, only risk.
The fact that they only opt-out EU users, because regulation forces them, tells you all you need to know about the moral compass of PostHog.
This shouldn't even require regulation, but apparently expecting companies to act morally is a bloody pipe dream. Profit over morals and concerns for your costumers, apparently.
as a user i dont like it, and am disappointed. it will take a bit of time to transition our systems off of posthog, but we will need to.
if you are looking at your metrics, I want to be clear that this transition will not happen overnight, but it _will_ happen for this reason, so just be aware that your short-term metrics won't tell the full story
What a great reminder to build my own analytics and self host. PostHog just lost a customer. They could easily send a email to each customer asking if we want this. The assumption means they have no product intuition about their own customers, let alone the customers of their customers. Bye.
Not trying to be snarky but why not just opt out instead of vibe coding your own analytics platform? I'm uncomfortable with people using my data to train AI, but those concerns revolve around where my data goes, and whether I'm notified/aware. Posthog is giving me good answers to those questions here.
It has to do with the priorities of the company and its leadership. Either they lack the basic awareness to know that training on your business customers data will likely leak their sensitive information to their competitors, or they just intend to sell that data. We are not paying to have our data stolen.
Thanks for posting. I had been in the fence for the past few months of switching. The new AI products combined with the weird UIs had been irking me for a while. This is the final nail in the coffin. Opt-in is a terrible business model imo.
Agreed. While I don't entirely care enough to rip it out of any existing products, I certainly won't be adding it to any new ones.
I remember people cheering about their "OS" web redesign, which was the most confusing and unnecessary UX complication when I needed to go track down a session replay to debug something (They've since added navigation to the top right.)
This should be a lesson in bad communication. Not being clear about whats being trained on is a huge mistake. And this announcement really puts into focus the drawbacks to PostHog’s cringe forward brand ethos
It's probably very obvious by now, but there's something to be said about companies with the "SF Quirky" vibes:
- The OS Redesign
- "Sexy Legal Documents"
- Emails with "<relevant hedgehog meme goes here>" as the subject line
- Having a merch shop with action figures of your CEO
It works both ways. When you're looking for adoption and making very pro-user moves, I guess it can be a benefit. However, when you're now looking to grow revenue and making very anti-user moves, it's insult to injury.
I'm the last person to say that tech "shouldn't be fun" or something overly-broad like that, but if your messaging doesn't match the decisions of leadership, you're gonna have a bad time.
> Put simply, because otherwise we will not have enough data to train a model that's actually useful.
Hmm, when asked to opt-in to giving their data away for yet another AI non-service, people don't want to. That's strange! The only way to get their data is to assume you can take it and force them to tell you to stop. Wonder what that could mean? Oh well, it's a mystery no one will be able to solve.
Yeah, the legislation is morally defensible on its own terms. But when you look at the full system, something funny happens:
EU legislation is blocking data extraction and platform lock-in tactics that Big Tech already used to become monopolies.
And since the big platforms don't have to unwind their advantages or pay back for the methods that are now restricted and considered illegal, they can peacefully extract rents from their entrenched positions for even longer, while everyone else is prevented from using the same ladder they climbed.
Every last single cent of that "economic development" is in the hands of billionaires, at least people in Europe have rights and their government isn't a couple of monopolies in a trenchcoat.
Why won't companies explain what anonymisation means for them?
Posthog has unfettered logged in access to some sensitive stuff. What steps are they actually taking to scrub sensitive data from my replay before being used to train a model?
this is what triggered my post. The announcement pretends that it's not bug deal because of "anonymization" but that's easier said than done. You can send custom events and logs that contain confidential information even if it doesn't contain personal identifiers
They say, "our goal here is to improve PostHog as a product for our customers, not to expose or sell models trained on your data" but then don't actually list that as a limitation in the bulleted points.
AFAICT this now gives them default permission to train an LLM on your code (as Posthog telemetry data is inextricably tied to your code) use it, and even sell it if they wanted to (as it's not your data anymore, it's their model). Yikes.
Posthog still cannot fix bugs that exist there for years and still cannot fix their identification process for merging users, but who cares right? Lets slop some AI on top of a non-working project. Good thing
Even if there were no AI, that's not any different than any SaaS where your data gets stored. Picking at random, Optimizely certainly has a ton of interaction data available and they build new features and products that leverage your data (without which the features would be impossible). Could be reporting tools, funnel analysis, etc.
Perhaps if they hopped on a quick call for five minutes with some customers, they'd realize quite how little appetite there is for putting up with being opted into things automatically in the US but not in the EU.
As an aside, this also means the EU rules are working.
Friendly reminder that you don't have to enable PostHog replays at all. I have a site lightly instrumented server-side with the slim bundle, and I'm still gonna double check my account settings but I'm pretty sure it's not even capable of doing the replay telemetry.
I initially used Posthog as an alternative to Google Analytics with more privacy. Now they want to use the data for a business purpose. Working hard towards enshitification?
I feel that the US should step up their legislation game and make sure these companies can't retroactively make rules to steal their users data.
I know it's trendy to hate the EU but their legislation actually protects the users, and not the companies interests.
Today I was thinking, if I start a company in the LLM tooling space, I would put in the company mission in the incorporation documents that client data will not be used to train.
The temptation and the value is too great, and the opt-in opt-out consent thing ends up being a fuckery where the company tries to trick the user into allowing them to take a look into the data, presumably because they are selling the product at a loss and need an alternative revenue model.
Just make it impossible from the get-go, the fine print would be that the data can be shared off-band explicitly, in an email, or if explicitly copy pasted in a support chatbox, but there would be no mechanism for us to read the data from the databases much less from the client.
I don't mean it would be an air-tight mechanism like Signal or ProtonMail, if a court order would ask us to produce client info, we would still reserve the right to produce the data, but exceptionally, and definitely not for training models.
More companies need to make, for lack of a better term, "oaths" of what they won't do as a company. My pitch on it is to tie it to financial penalties the company agrees to pay, somewhere in the "enough to incentivize a significant portion of our user base to sue us" territory, such that it would be financial suicide to violate them.
Contracts ad incorporations are designed for this, the issue is that the incumbent legal strategy is to use template documents, and to reduce potential disputes to 1$ in private arbitration, essentially legal's job is to make legal go away.
Another term I would incorporate is a Seppuku term, if we get hacked, I resign, the company goes bankrupt. Anything else is the wrong attitude to computer security for companies that want to scale to Global reach.
PostHog better transition to an AI company soon because they are one of the SAAS's which are absolutely cooked by vibe coding. What it does is extremely amenable to LLMs and it's also non-critical for a business, making it an excellent candidate for replacement by in-house solutions. And if it means never having to use their website again that's even better.
I wonder if they regret opensource, considering people will be using LLMs to replace them which have surely trained off of their code.
“Opt-in by default” is an oxymoron. If it’s default then I haven’t opted into anything. It’s been enabled by default.
This frustrates me too, if something is "opt-in", that means by default you're not included and can choose to be included. If something is "opt-out", that means you're included and can choose not to be.
But then it gets used to describe the reverse, and we have to add words to clarify.
I once saw a post here with a correctly described opt-in telemetry before, and the top comment here was attacking them for the reverse, thinking it was including them by default, so there's little winning, it's one of those words that has just come to mean it's opposite.
“Opt-in by default” is just Opt-out. We already have the term.
They are opting you in by default. Very cool.
Never miss opting in to newsletters again with NewsAI! NewsAI automatically opts you in to thousands of newsletters and marketing campaigns around the world in an instant!
But that's not the standard definition of "opt-in". See for instance MW: "to choose to do or be involved in something".
Yes, we know. It was sarcasm.
Isn't it kind of like mandatory tip? If you haven't given it voluntarily, i.e .its automatically opted-in and you maybe can't even not give it. its the same.
Many restaurants have the audacity to add a 20% (or whatever percentage) "service fee" that isn't considered tip. It even says something like "we use this to pay our staff competitive wages and health insurance." You can't opt out. It's just part of the bill. Then they have the gall to ask for a tip on top of that.
I've taken to a) leaving a negative Google or yelp review for such establishments and b) never coming back. This is a practice that needs to die.
Do you leave a negative review if they add the service charge but don't ask for a tip?
I've never had the pleasure of encountering that situation.
But at what point do we call a spade a spade and say it's just them secretly inflating their prices? "everything is a penny but we charge a 1000000% service charge"
I used to wait tables once upon a time and it was standard practice to add a fixed service charge for any large party in lieu of a tip. Have you really never encountered that?

The average consumer can't do math.
I would. If it's mandatory just include it in the advertised food prices.
Opt-in by default means it is either mandatory (if you can‘t disable it) or it‘s opt-out (if you can) Opt-In by default is BS to make it sound less invasive
Imagine if they said paying taxes were opt-in by default. No, it's mandatory! Sure you can technically not pay taxes but you won't have a good time.
That is slightly different though. The government says you must pay taxes, mandatory as you said.

Very true. I was considering PostHog, but this sours them in my eyes. Very deceptive wording.
They could’ve done a lot worse, and most companies would’ve.
There's a helpful response. It could always be worse!
You were given the option to option in, by default. Clearly it makes sense, optioned out by default only happens when someone loses money on the option in default instead.

I'd recommend at least doing a short spike to see if you can build your own in some way. We did that for the purpose of experimentation and now we've built our own metrics platform that we completely own.
this is the business model of all companies training AI, if they had to get permission we wouldn't have frontier LLMs at all
So it's OK to do stuff without permission as long as we get something that makes a lot of people a lot of money?
It's not OK, but it's a fact.
*"that makes a select few rich people a lot more money?"
has it not always been this way?
Two things can be true. A shitty thing can prevail for a long time and still be shitty.
> if they had to get permission we wouldn't have frontier LLMs at all
Don't threaten me with a good time.
That would be a good thing TBH.
Defaults matter.
Opt-in vs opt-out organ donorship has a large impact.
Most people on any web app won’t stray from the defaults.
I sincerely hope this never comes to pass, but you or your loved ones may someday find themselves in the position of wishing more people were opted in for organ donation.

> half-alive state
The brain can't be "half-alive" after you've died.
> I do not think we understand consciousness enough to rule out what those brains are experiencing.
The parent edited their comment, wasn’t there when I replied. But if you believe your organs don’t die when you die, then don’t donate your organs?
Organ donation saves lives at no cost to you (because at this point you're dead).
It's unclear if my private data being used for training has a cost to me, but I'm giving posthog money already. They shouldn't double dip.
Again, this is because it's uninformed.
Consent matters.
yea except one is a "dark pattern" to exploit customers for corporate profit while the other is to benefit society.
There is no such thing as opt in by default - and burning that amount of customer goodwill because you want something instead of say, giving a discount to people who are willing to do it is a choice for people who have a lot more market share and their customers would have more trouble leaving.

Cant wait to see posthog crash and burn, i have hated their service for years now.
why?
Bizarre take.

That's actually an interesting note. So you all will be managing the training runs on hardware you own or rent and manage?

This is slimy.
It's slimy because your government allows it, this doesn't have to be the case.
1. Lobby your representatives to improve your data protection laws, even if you think it's pointless to do so
2. Stop attacking EU data protection laws, even if they inconvenience you
As can be seen from this announcement, data protection laws do make a difference.
I don't want to support a company that's going to do everything they can possibly legally get away with, I want to support companies that do the right thing where they can.

I remember people cheering about their "OS" web redesign, which was the most confusing and unnecessary UX complication when I needed to go track down a session replay to debug something (They've since added navigation to the top right.)
This should be a lesson in bad communication. Not being clear about whats being trained on is a huge mistake. And this announcement really puts into focus the drawbacks to PostHog’s cringe forward brand ethos
It's probably very obvious by now, but there's something to be said about companies with the "SF Quirky" vibes:
- The OS Redesign
- "Sexy Legal Documents"
- Emails with "<relevant hedgehog meme goes here>" as the subject line
- Having a merch shop with action figures of your CEO
It works both ways. When you're looking for adoption and making very pro-user moves, I guess it can be a benefit. However, when you're now looking to grow revenue and making very anti-user moves, it's insult to injury.
I'm the last person to say that tech "shouldn't be fun" or something overly-broad like that, but if your messaging doesn't match the decisions of leadership, you're gonna have a bad time.

Hmm, when asked to opt-in to giving their data away for yet another AI non-service, people don't want to. That's strange! The only way to get their data is to assume you can take it and force them to tell you to stop. Wonder what that could mean? Oh well, it's a mystery no one will be able to solve.
“Opt-in by default” = opt-out?
Guess its "Opted-in" by default
Then it’s not opted. It’s just in.
"Possible to somewhat disable", I call it "PTSD".
Opt means to make a choice or select an alternative. They are either incompetent or lying on purpose.
Every day I'm more glad about EU legislation, that's all I have to say for now
Yeah, the legislation is morally defensible on its own terms. But when you look at the full system, something funny happens: EU legislation is blocking data extraction and platform lock-in tactics that Big Tech already used to become monopolies.
And since the big platforms don't have to unwind their advantages or pay back for the methods that are now restricted and considered illegal, they can peacefully extract rents from their entrenched positions for even longer, while everyone else is prevented from using the same ladder they climbed.
...until you learn the rates of economic development between Europe and the US since 2008.
Every last single cent of that "economic development" is in the hands of billionaires, at least people in Europe have rights and their government isn't a couple of monopolies in a trenchcoat.
That is a doubly naive pair of statements.
How many Yankees can get treatment for say cancer without going bankrupt?
Yes the amount of fiscal growth in America is very impressive. Yet quality of life is higher in Europe. I wonder why that is?

AKA we won't be able to make as much money if we required you to give us permission to use your data.
Why won't companies explain what anonymisation means for them?
Posthog has unfettered logged in access to some sensitive stuff. What steps are they actually taking to scrub sensitive data from my replay before being used to train a model?
this is what triggered my post. The announcement pretends that it's not bug deal because of "anonymization" but that's easier said than done. You can send custom events and logs that contain confidential information even if it doesn't contain personal identifiers
"Training won't start until June 29, so there's plenty of time to decide"
...except, we have made the decision for all the US customers already. Nice.
They say, "our goal here is to improve PostHog as a product for our customers, not to expose or sell models trained on your data" but then don't actually list that as a limitation in the bulleted points.
AFAICT this now gives them default permission to train an LLM on your code (as Posthog telemetry data is inextricably tied to your code) use it, and even sell it if they wanted to (as it's not your data anymore, it's their model). Yikes.
Posthog still cannot fix bugs that exist there for years and still cannot fix their identification process for merging users, but who cares right? Lets slop some AI on top of a non-working project. Good thing
How much are they paying the users?
All of them do if you don't do something about it(e.g. migrate to self hosted solutions), trusting a ToS in 2026 is as naive as it gets.
I’ve been evaluating PostHog for our company.
I’ve now made our decision. We won’t be using them.
If they are going to position yourself as the non-slimy no-BS guys, they can’t pull this nonsense.
Mostly unrelated but the name of this company makes me think it's a Dick-Pics-as-a-Service provider.

This is totally intentional and they play it up for all it's worth on their bus ads in SF. Personally I find it just pathetic, but what can you do.
Gross.
They’ll use your product and your data to later sell a product back to you.
Even if there were no AI, that's not any different than any SaaS where your data gets stored. Picking at random, Optimizely certainly has a ton of interaction data available and they build new features and products that leverage your data (without which the features would be impossible). Could be reporting tools, funnel analysis, etc.
Perhaps if they hopped on a quick call for five minutes with some customers, they'd realize quite how little appetite there is for putting up with being opted into things automatically in the US but not in the EU.
As an aside, this also means the EU rules are working.
+1 this made me glad we opted for the EU region
This is the fastest way possible to ensure I will never do business with you, or stop doing business with you if I already am.
posthog have lost the plot
Friendly reminder that you don't have to enable PostHog replays at all. I have a site lightly instrumented server-side with the slim bundle, and I'm still gonna double check my account settings but I'm pretty sure it's not even capable of doing the replay telemetry.
You can’t “opt-in” to something that is the default. The choice is made for you — and when the choice is made for you? You haven’t opted in or out?
I would have guessed that was just a bad title here but no, article states it as "opted in by default".
I fixed the title, sorry for the typo!
not your fault, the article uses that language!
I initially used Posthog as an alternative to Google Analytics with more privacy. Now they want to use the data for a business purpose. Working hard towards enshitification?
> I initially used Posthog as an alternative to Google Analytics with more privacy.
This does not make any sense.
> Now they want to use the data for a business purpose.
They raised VC money and they want a return so this was predictable.
It makes perfect sense actually
I feel that the US should step up their legislation game and make sure these companies can't retroactively make rules to steal their users data. I know it's trendy to hate the EU but their legislation actually protects the users, and not the companies interests.
Today I was thinking, if I start a company in the LLM tooling space, I would put in the company mission in the incorporation documents that client data will not be used to train.
The temptation and the value is too great, and the opt-in opt-out consent thing ends up being a fuckery where the company tries to trick the user into allowing them to take a look into the data, presumably because they are selling the product at a loss and need an alternative revenue model.
Just make it impossible from the get-go, the fine print would be that the data can be shared off-band explicitly, in an email, or if explicitly copy pasted in a support chatbox, but there would be no mechanism for us to read the data from the databases much less from the client.
I don't mean it would be an air-tight mechanism like Signal or ProtonMail, if a court order would ask us to produce client info, we would still reserve the right to produce the data, but exceptionally, and definitely not for training models.
More companies need to make, for lack of a better term, "oaths" of what they won't do as a company. My pitch on it is to tie it to financial penalties the company agrees to pay, somewhere in the "enough to incentivize a significant portion of our user base to sue us" territory, such that it would be financial suicide to violate them.
Contracts ad incorporations are designed for this, the issue is that the incumbent legal strategy is to use template documents, and to reduce potential disputes to 1$ in private arbitration, essentially legal's job is to make legal go away.
Another term I would incorporate is a Seppuku term, if we get hacked, I resign, the company goes bankrupt. Anything else is the wrong attitude to computer security for companies that want to scale to Global reach.
another would be excellent product company destroyed or being destroyed slowly due to VCs and the ever chase for 'growth'
The enshittification has begun. Time to move on!
PostHog better transition to an AI company soon because they are one of the SAAS's which are absolutely cooked by vibe coding. What it does is extremely amenable to LLMs and it's also non-critical for a business, making it an excellent candidate for replacement by in-house solutions. And if it means never having to use their website again that's even better.
I wonder if they regret opensource, considering people will be using LLMs to replace them which have surely trained off of their code.
LOL. You stay classy PostHog.
