Do you mind expanding on why that is? Is it because it allows them to say "well the API told us they're adults so we're all good"?

and the verification that the OS has to provide is minimal. the OS doesn't need to verify and ID or anything. Probably just a checkbox when you create the account that you're an adult, or child, etc. and then that's provided to the browser. So it effectively becomes meaningless if the goal is to get children off social media.
