Felt same way about GrapheneOS but a few friends set it up so i gave it a try. It is easy to install and use. As evidence, I gave my 70 year old father one and he loves it.

Can you run Graphene on non Pixel phones?

You can use Lineage [/with microG]

Really, how? At some point someone will need to issue a key, which at some point will need to be verified against known good signatures. These signatures will also need to be kept in case of lawsuirs/enforcement, so if somebody gets access they will know you visited that site

With cryptography. Look at e.g. Privacy Pass, there is an RFC about it.

Ring cryptography does this - given a public key and a set of private keys you can attest that one of the keys signed it but not which one. This lets both Google and you generate a signature and say “this is attested”, without the person verifying it knowing _who_ signed it.

Parental controls on device are a better solution that work today and don't carry a risk of data breach.

Everyone, including Linus Torvalds, who rejected Stallman as too political or ideological, and advocated for "pragmatism" instead, is part of the reason we're where we are today. And it's going to get a lot worse, before it ever gets better.

I disagree. The reason we are where we are today is the lack of antitrust.

Even if we accept your premise, laws don't just appear; they are an organized response to a recognized problem. But everyone has been sleeping on the problem lurking in our infrastructure, undermining any impetus to enact such laws. And the people screaming from the mountain top (like Stallman), trying to raise awareness, were routinely mocked and marginalized by those all too happy to accept convenience and expediency, over more sustainable values.

They would be a solution if almost all parents used them, but parents don't want to socially isolate their kids since a lot of "social" activity is now on social media. It's kind of a prisoner's dilemma.

There's not necessarily wrong. Despite the vapid and damaging nature of most popular online media, isolating a child from it might have even worse social consequences when their real-life peer groups discover that they're not on social media or that their parents have neutered their phone. Some kids would turn out fine after that. Others would be socially destroyed for life (maybe with the right therapy they could become well-adjusted, but high quality therapy is rare).

The trick is to define "privacy-preserving age verification" in an extremely narrow way that ignores any other privacy concerns.

For example, imagine you put the same private key into the 'secure element' of every single iphone. You use code signing so that key is only unlocked when the phone is running unmodified iOS with all security updates. You use encryption and remote attestation for the front-facing camera and face id depth sensor. You use NFC to read government-authenticated age and appearance data from biometric passport chips (or digital ID cards) and you store it on-device.

Then, when you want to access pornhub, they send an age challenge to your device, your device makes sure your face matches the stored passport, and if so it signs the challenge with the private key.

Pornhub gets an Apple-signed attestation of age - but because every phone signs with challenges with the same private key, Pornhub can't link it to a particular phone or identity document.

So in a very narrow sense, privacy is preserved.

You can't use someone else's ID, as it checks your face every time. You can't fool it with a photo of the person because of the depth sensor. You can't MITM/replay the camera/depth data because the link is encrypted. You can't substitute software that skips the check with a rooted phone because of the code signing. Security holes can be closed by just pushing a mandatory OS update.

Sure, it doesn't work on PCs. Doesn't work on Linux, or on unlocked/rooted phones. It hands users' government ID documents over to Google and Apple. It requires people to carry foreign-made, battery powered, network connected GPS trackers (with cameras, microphones and speech recognition) with them. And there are non-negotiable terms of service everyone must agree to. But if you define "privacy-preserving" to ignore all that stuff and only consider whether Pornhub learns your identity, it's privacy-preserving.

Stop visiting sites and using services that use reCAPTCHA. Problem solved.

That's great until it's some essential government, medical, educational, etc. service that you have either no alternative to or no alternative that isn't also using the same thing. I'm already being slowly and incrementally softlocked out of some (fortunately non-essential so far) sites either by cloudflare or other more subtle "anti-bot" networks as time goes on, including some like I've listed above. I can only exp…

For some reason, I'm softlocked from booking tickets from Deutsche Bahn. The website errors out with a cryptic "Your browser's behavior resembles that of a bot." message with no option to try again or pass a captcha or whatever. The website itself described several possible solutions but none helped (I tried using different computers, different internet connections, even a phone connected to internet using a SIM from a different country).

As for now, when I need to travel to Germany, I just book tickets through the national carrier of my home country, which for cross-border tickets often turns out to actually be cheaper than booking through DB. Thankfully I don't live in Germany proper and my need for travel there is not that high (once or twice a year at most) but I wonder what would I do if I had to move to Germany and use trains there more often.
