> We all know parents are far more likely to tap "OK" for "Allow personalized social feeds?" than they are to knowingly falsify their kids' age.

I know lots of parents and lots of kids, and I don't think this is accurate. In my experience the breakdown is parents who care what their kids are doing online, and parents who assume it will all turn out fine because they had AOL or even Facebook as teenagers and didn't get into too much trouble. The first group is already keeping an eye on their kids and might even have decent parental controls set up, and the second group doesn't care what happens as long as charges don't show up on the credit card.

These bills punish the first group of parents and OS/device makers for the transgressions of social media companies. The uninvolved parents won't even be in the room when the age question comes up.
