What is the point of it? If the are doesn’t cryptographically trace to the right birth certificate for who is at the keyboard now it won’t do anything - kids will lie about age if there is any issues. If it does trace back that well there are huge privacy problems.
where do the maitainers of the linux distro of your choice live? I mean every single person because if even one lives in CA (Brasil…) you have to either ‘fire’ that person or follow the law for their sake. I agree systemd shouldn’t be the place for this, but systemd wants to take over everything and I’m sure some of their maintainers live in CA thus they feel they must.
It won’t protect children, but you can’t igore the law. You can get lawyers and fight that way. However too many eevelopers live in CA to ignore and every one of them is at risk of the law going against them. Small distros can say they don’t have anyone who maintains it in CA so the don’t allow their distro to be used in CA. Large ones cannot ignore the law just because it is stupid and won’t work.
