That is not something that should be controlled by an IT company, ISP, or an OS. I think parents have a responsibility to control (or at least influence) their childeren's content consumption. Companies like Google and Apple provide built-in parental controls and digital wellbeing apps, you can also use something like OpenDNS or control it via some other means. If a kid has unrestricted internet access and screen time, the parents are being neglectful. Obviously there should be some regulatory action to force companies to not make their apps addictive or harmful in some ways (including to minors), but not through age checks in an OS... The bill is kind of confusing, but from what I understand, it doesn't require ID checks, so as a convenience to not have to worry about kids having access to things they shouldn't it is not that awful (just put any age number you want when configuring OS). But implementing this is impossible (how do you force all programs to not show things that are not for "a user is in any of several age brackets"). It shouldn't be an OS requirement, maybe an optional feature that the state advises major OSs to have. Also some OSs are not for personal use, and nowadays a toaster may have an OS...
