Reading the comments here, I see a lot of criticism along the line of "age verification doesn't work, it's completely stupid".
I believe it is counter-productive, because "not having age verification" is a lost battle. Unlike E2EE (where it is impossible to give access "only to the good guys"), it is possible to implement age verification in a privacy-preserving manner. And look at the ChatControl fight: even though it is not possible, we are still struggling to convince politicians of it. Good luck with age verification where it is actually possible to do something.
It should be a public service: just like the government issues IDs already, it should run the privacy-preserving system that allows citizens to prove their age. We should fight for that, otherwise we will get non-privacy-preserving systems managed by private companies (which is already starting).
I'm writing my (Canadian) MP to this effect.
There are a lot of issues with the UK approach. Privacy is a big one. But requiring this on every service is both a tax on the service and requires constantly authorizing stuff. That opens up the possibility for scams, data misuse, etc.
And no, saying we said to only use the data for verification clearly doesn't work. It didn't work for discord, or Persona, or Tea or AU10TIX or any others. Verification now means sharing that data with credit agencies and third party databases. Verification means keeping some data to resolve customer support disputes. There's data leakage for training and creating derived data products like biometric embeddings for future use.
Third party verification is a security nightmare.
I don't know why device based approvals abd controls aren't considered at all. Or really any privacy preserving technique.
And all this for ~54% efficacy?
That won't happen. Because the intent of the people pushing for "age verification" has nothing to do with the "think about the children" moral panic. It has to do with eliminating encryption and eliminating online anonymity. It is a dog whistle.
