If you actually read this law, it does exactly the opposite to avoid every random app/website from having to do age verification (like traditional age verification laws requires). It requires that only the OS to ask the user's age (not even verify it). Individual apps should use the age buckets signaled by the OS.

I don't even get why people think lobbyists hijack the law. It might be too left/progressive/socialism/or whatever. But, basically, the only major org opponent of this law is Google: https://calmatters.digitaldemocracy.org/bills/ca_202520260ab...
