First of all, age verification is not mass surveillance, it is possible to verify your age without disclosing who you are to the site you're visiting, and without disclosing what site you visited to the government. There are even age verification services (and I do despise them fully, this should be a government provided service!) that use only facial features to determine your age (you can call it surveillance, but not "mass").
See, the thing is, no matter how good your intent is, no matter how noble your cause, if you use lies and half-truths to further your argument or resist change, it only serves to undermine it all. For example "They do not deserve surveillance," is so disingenuous, if a site is required to verify age, the only children whose age might be verified are those who might have been exposed to that harmful content otherwise anyways, they're not being selected for surveillance, no one is trying to spy on children (or could possibly benefit from doing so using this method, since it is so unreliable), but they're framing it as it is so.
This isn't like "DRM" or "the nsa is spying on everyone", and there is a big difference between Signal (how are they involved in all this? is this just opportunistic politicking?) being required to verify peer-to-peer messaging from a porn site or or a live-cam site for sex workers requiring both parties to be age verified (where children do get trafficked!!).
Don't get me wrong, I don't like the idea, i really hate it but the prevailing positions in areas of the internet like here is so irrational and unreasonable.
You can't flash your private parts at children, you can't take children to a strip club, they're required by law to check IDs (even night clubs are!!). if that same interaction happens on the internet, suddenly no age verification is needed?
Is it because this problem has been left unaddressed for so long that so many are just too used to "the old way of doing things" despite the ever increasing human suffering caused by lack of regulations and laws like this?
I hope legislators grow a pair and stand up to these tech-crusaders who will burn down the world so long as they feel their corner is safe and secure.
Shame on everyone who refuses to have a nuanced discussion on this and instead takes an all-or-nothing position against any sort of legislature that would reduce (not eliminate) the harm being done. To mean, such people are no different than catholics, teachers, administrators, and anyone else in a position to do something about harm against children but turned the other way because their little world would be too shaken otherwise. Hiding behind "mah privacy!!" doesn't absolve you of the responsibility to at least attempt to be nuanced about it, at least propose an actual solution instead of just "I don't what the solution is, but not this" or "parents are at fault, I don't care" or something lazy like that. I wish I didn't know that when it comes to their own interests, wannabe technocrats like these are ingenious in developing tech like homomorphic encryption, differential privacy and zero-knowledge-proofs; this isn't about anyone's privacy or mass surveillance, it's about preservation of the status quo, apathy and faulty slippery-slope fallacy thinking.
