I mean, if someone was on a street corner selling child friendly cigarettes, I wouldn't call that a parenting issue.

I think parenting is one aspect, but surely you see how given it's a platform that advertises itself specifically for children, in the same way as if there was a children channel on the TV telling your kids to smoke crack, maybe someone should step in

Yea, we'd charge the person on the corner selling the cigarettes. We wouldn't sue the city for selling cigarettes just because it happened in the city, even if the person selling them paid their taxes (so the city made money on it).
