What I'm reading of this law is that it requires OS developers to require users select their age (really their age bracket) when making a user account, and an interface for applications/websites to read that user-provided field. I.e. not age verification, but just a standard way to identify if a user is on a child account. If that understanding is correct, how is this bad at all? It's a way to put to rest people's concerns and pearl-clutching over children accessing adult content without every individual app and service provider contracting with Palantir to scan you and guess your age. Instead they can just read the IsAdult header and call it a day. What's the cost to user-freedom? You have to be presented a Date of Birth field or I Am an Adult / Teen / Child selector when setting up a device... a thing that every operating system impacted by this law already does.
