* This approach is the _most consistent_ with retaining anonymity on the internet, while actually helping parents with their issues. If any age-relevant gatekeeping needs to be made on the internet at all, this is the one I find acceptable.
* this is because the act very specifically does NOT require age _verification_ ie using third-parties to verify whether the claimed age is correct. Rather, it is piggybacking on the baked-in assumption, that parents will set up the device for their kids, indicating on first install what the age/DoB is, then handing over the device -a setting which can, presumably, only be modified with parental consent
* yes, there are edge cases, esp in OSS, and yes, it would be nice to iron those out -but the risk = probability x impact calculus on this is very very low.
* If retaining anonymity on the internet is of value to you, don't let the perfect be the enemy of good enough.
