There are two things very very wrong with the California law, which you call "age indication".
1) The parental responsibility is given to the wrong people. You're basically being forced by law to give all apps and websites your child's age on request, and then trusting those online platforms to serve the right content (lol). It should be the other way around. The apps and websites should broadcast the age rating of their content, and the OS fetches that age rating, and decides whether the content is appropriate by comparing the age rating to the user's age. The user's age, or age bracket, or any information about the user at all, should not leave the user's computer.
2) The age API is not "completely private". It's a legally-mandated data point that can be used to track a user across apps and websites. We must reject all legally-mandated tracking data points because it sets the precedent for even more mandatory tracking to be added in the future. We should not be providing an API that makes it easier for web platforms to get their hands on user data!
For many years, certain tech companies, SIGs, and governments have fought against technologies that could enable real digital parenting, all while claiming to do the opposite and "protecting children". They craft a narrative to convince you that top-down digital surveillance and access-control is for your own good, but it's time we reject that and flip their narrative upside down: https://news.ycombinator.com/item?id=47472805

FWIW, this is not quite an accurate description of AB1043, in at least three respects:
1. Apps don't get your exact age, just an age range.
2. Websites don't get your age at all.
3. AB1043 itself doesn't mandate any content restrictions; it just says that the app now has "actual knowledge" of the user's age. That's not to say that there aren't other laws which require age-specific behaviors, but this particular one is pretty thi on this.
In addition, I certainly understand the position that the age range shouldn't leave the computer, but I'm not sure how well that works technically, assuming you want age-based content restrictions. First, a number of the behaviors that age assurance laws want to restrict are hard to implement client side. For example, the NY SAFE For Kids act forbids algorithmic feeds, and for obvious reasons that's a lot easier to do on the server. Second, even if you do have device-side filtering, it's hard to prevent the site/app from learning what age brackets are in place, because they can experimentally provide content with different age markings and see what's accepted and what's blocked. Cooper, Arnao, and I discuss this in some more detail on pp 39--42 of our report on Age Assurance: https://kgi.georgetown.edu/research-and-commentary/age-assur...
I'm not saying that this makes a material difference in how you should feel about AB 1043, just trying to clarify the technical situation.
1. I don’t see how that’s better in any real way. You can infer the exact same information as querying the range and it makes dynamic behavior based on age range (ex. access to age restricted chat rooms as an obvious example) completely impossible.
2. Is it meaningfully more identifying than User-Agent? There’s dozens of other datapoints for uniquely identifying a user. If we get a few high profile lawsuits because advertising companies knowingly showed harmful ads to children, I’d consider it a win. Age is not that interesting of a data point.

How would you make that happen? Many websites would not be subject to your jurisdiction.
