It does not stop at the check box. Someone is going to sue Google/Apple when a 13 year old gets on a porn site. Then Google/Apple will introduce "verification" that requires linking your identity to your device, and attesting this to the "operator" (porn site). Then every person using any OS is tracked, on every website and app, all the time, by law. And Linux becomes illegal without it.

This is not a theory. Laws requiring this are going through the state and federal level right now.
