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.
Why should it be law? I am a developer in California, and a long time Linux nerd. If I were to release a hobby on my GitHub for fun, without age verification, am I now subject to fines? Imprisonment? Why should their be a legal requirement?
All the better to do targeted advertisments and underdeveloped minds!
How is this good at all for a free society? You are basically making a "what about the children?" argument. its the parent job to protect their children. why should anyone suffer this b.s.?
It's not enough to just accept the age signal:
> (3) (A) Except as provided in subparagraph (B), a developer shall treat a signal received pursuant to this title as the primary indicator of a user’s age range for purposes of determining the user’s age.
> (B) If a developer has internal clear and convincing information that a user’s age is different than the age indicated by a signal received pursuant to this title, the developer shall use that information as the primary indicator of the user’s age.
Developers are still liable if they have reason to believe someone is underage, even if the age signal says otherwise.
The only way to truly minimize that liability is forcing users to scan their faces and IDs, that is why age verification systems are already implemented that way.
