This thread has been sneeding about this shit for a week straight and it seems like half the people here, and most of the people talking about this elsewhere, don’t realize they’re not actually asking you to give anyone your ID. The whole thing is about a piece of user-supplied data, whose reliability is entirely dependant on you. The point is to have a single consistant answer to that question for any specific user, ideally set by an administrator in the case of child user, rather than applications independantly asking the user how old they are every time they need to know.
These laws shouldn’t exist, but also this shit is not the end of the world. My google account says I’m ten years older than I actually am, the same is probably true of lots of you. Maybe this will lead to more restrictions in the future, maybe this will be considered enough. Noone knows what the future will hold (although not trusting governments wrt this is a safe enough bet).
