We don't police big tobacco very well on making their products more addictive. We seem to be fine with expanding gambling - where I live (not Nevada!) slot machines are everywhere. Nice restaurants even will dedicate corners to slot machines - not just seedy bars. Sports betting apps are all over streaming ads, and their legality is expanding even though when they are legalized in an area the divorce and loan default rates go up measurably.
Why would we regulate big tech if we don't bother with anything else?
The kids are just the latest victim of a long ongoing trend.
