CA age-checking law
I've read CA AB-1043¹ and as an innocent outsider some things strike me as alarming, apart from the whole idea:
* OSes aren't allowed to not answer or lie to nosy programs.
* programs must ask on launch and then are deemed to have "actual knowledge" of the person's age bracket, which sounds legally significant.
* there's no explicit carve-out for "not for use in CA" things.
* almost everything seems covered including eg the Debian package collection.
