> but to actually implement age controls in the way they are being bought in you basically need to be an authoritarian

I don't see how this sentence can make any sense at all in the context of ZKPs. Can you elaborate?

> you'd be persuaded by arguments like Mullvad's that the social media companies already know how old their users are and don't need a centralised authority to tell them

How do the social media companies already know? Because they track everything? But if they ban kids, they don't track them anymore, do they? Or are you saying that social media companies should be able to track everybody everywhere, such that they can profile them and ban them from accessing social media?

> I don't like it because, objectively, this is authoritarianism

You would have to explain that. The government provides a service that allows you to prove that you are old enough without the government learning anything from you and without the service learning anything other than the fact that you are old enough, and you call that "objectively authoritarianism"?

The reason people are getting called authoritarian is because ZKP proofs are a massive and obvious improvement on what is actually being implemented. Can you point to anywhere that has implemented ZKPs? The linked article suggests that is quite hard to do.

I wouldn't be using an American IP right know if my local age verification laws required ZKPs.

> How do the social media companies already know?

They ask you your age when people sign up. That's good enough for me - I'm not an authoritarian. I'm not out to create a watertight way to stop people communicating if they want to.

I haven't seen anyone complaining about that. Sounds like a non-issue. Why would anyone over the age of around 18 care? You should consider reading the linked article if you don't understand what the complaints people are making are. The reason you don't see any authoritarianism is you haven't actually looked at how the schemes are being implemented.

Mullvad isn't writing this blog post because of the huge numbers of 12-16 year olds shelling out cash to them. It is because the authoritarians are making a play to destroy a sizeable chunk of the open web with a likely follow up of cracking down on free speech.

The EU initiative explicitly mentions ZKP: https://ageverification.dev/.

It's technical, just like getting E2EE right. Doesn't mean it's hard to use, as proven by the fact that billions of people use E2EE in WhatsApp and Signal without even realising it.

> I'm not an authoritarian. I'm not out to create a watertight way to stop people communicating if they want to.

You seem to have a Manichaean view of the world. There is room for nuance between "let kids lie by clicking 'yes'" and identity verification.

> You should consider reading the linked article

Did you read it? There is a whole section that is titled "The Zero-Knowledge Proof alternative and the EU".

> The reason you don't see any authoritarianism is you haven't actually looked at how the schemes are being implemented.

I actually have. Have you? Seems like you haven't read the article. Mullvad is complaining about the fact that the app seems to support both ZKP and identity verification, and they criticise the infrastructure enabling identity verification. And then some more "slippery slope" arguments that are worth what they are worth (with the same kind of reasoning, we shouldn't have gun control, because the next step is to control everything, right?).

> Mullvad isn't writing this blog post because

Mullvad sells some kind of privacy (as much as a VPN can offer), and here they share their opinion about age verification. With which I mostly agree: the only viable age verification implementation is through ZKP. I tend to disagree with the slippery slope argument, and that "the government abuses everything they can". If you think like that, doesn't that make you an anarchist?

You have misunderstood the article. It says, and I quote,

> Right now, the EU app does not have ZKP functionality, contrasting Ursula von der Leyen’s claim that the app ”is technically ready to be used”. But more importantly, the app is currently designed to always function without ZKP technology; if ZKP is unavailable, the app falls back to a non-ZKP model.

So you have failed the test of pointing at somewhere that has implemented ZKP. You can try again if you like.

> I actually have. Have you? Seems like you haven't read the article. Mullvad is complaining about the fact that the app seems to support both ZKP and identity verification,

Again, this is factually wrong. And it is why people are getting labelled as "authoritarian" - they proposed a system that sounded decent, then they actually implemented something else that is a standard authoritarian ID system with a fig leaf for people to pretend they didn't. As was expected, given that this always looked like an ID card play with a false moustache.

> I tend to disagree with the slippery slope argument

They haven't made it up the hill yet, they're already down the slope. the EU implementation doesn't use ZKP. That's a big part of why they're being included as one of the authoritarian forces in this push that people are upset about.
