We absolutely need to make efforts to limit kids' exposure to addictive social media mechanisms.

People aren't generally against kids using the Internet to communicate; they are against giant tech companies using children as a captive audience without regard to how their decisions might hurt them.

If kids are misusing a comments feature as a general-purpose chat room, good for them. They figured out how to manipulate the system instead of letting the system manipulate them.

Regardless, we need to regulate social media so that it doesn't harm children, and we need to do so without sacrificing the privacy of every adult (age-gates don't work).

This is why we need to rename "social media" to the more accurate "antisocial media". I think everyone reasonable wants kids to be social with each other.
