That's not my understanding. This is what the bill says: Provide a developer who has requested a signal with respect to a particular user with a digital signal via a reasonably consistent real-time application programming interface that identifies [the age group].

So the app requests a signal (like, calling an API), and the OS returns the signal (returning the age group).

Regarding API vs installation lock, TBH I don't think the law concerns that level of details. An OS or app-store installation lock that checks app ratings can be considered as a valid implementation.

The California law is horrible because it forces everyone to let tech companies and governments decide what's suitable for children, rather than let parents decide. It's telling parents to give every app their child's age and trust that the apps will do the right thing. It also legitimizes personal data collection (in this case, the user's age) for every app and service on the Internet that wants to know your age.

The password-based app installation lock I proposed in my original comment doesn't require any kind of age checking at all, so it naturally doesn't fit the California law. The device owner (in this case, the parent who buys the device for their child) gets to decide what apps can be installed on their child's phone on an app-by-app basis using a password set by the parent. The app store doesn't need to know, and the apps don't need to know.

You have a point. Though I suspect that average parents are either too lazy or not tech literate enough.

I do want to note that this California law alone doesn't say anything about content restriction. I won't be surprised if there was/will be another bill to assign the responsibility (which may be more controversial). But the current law is only about the age gating mechanism. And on the positive side it removes the need for actual age verification (like using ID) which other regions still insist on.

The California law is the closest thing to what we do in the physical world but better. We already decided as a society to limit the purchase of pornography, gambling, alcohol, tobacco, prostitution, drugs, via age gates and require the merchant to be liable for that. We already find this reasonable as a society. The California law recognizes the tracking problems of requiring a verifiable id online and instead recognizes that parental self-assertion at the point of account creation is enough.

Since tracking children is generally illegal, you can also voluntarily lie and label yourself as a child when you don't want to access such content.

We have decided as a society to age-gate the purchase of a very small selection of goods and services, but this did not require a law that says all merchants have the right to know your age. And in this case, it's not even just all merchants, but anyone that serves you any kind of information. The real world equivalent of this California bill would be more like: anyone you've ever talked to has the right to know your age.

A more reasonable approach would be for parents to keep tabs on (or for stricter parents, control) who their child is associating with and where they're going, and advise their child on who/what to stay away from if they're out alone. And of course that takes parenting effort. The digital equivalent of this are things like password-gating app installation in the OS and website-blocking in the WiFi router. But I will say, I don't think these kinds of analogies are good because the Internet is too different from the physical world.

And let's not underestimate the tracking power of a legally mandated data point: the age contains about 6 bits of information that can be used to identify your user account on the Internet across apps and websites, even if your inputted age is fake.
