> What wave of efforts is culminating? I can't really explain this from any movement I can see.

Look at any thread about social media, TikTok, smartphones, or porn sites on Hacker News: They are instantly filled with comments claiming that the internet is to blame for all of society's ills with younger generations. The HN threads fill with comments proposing that we ban children from having smartphones until they're 16 or 18 and similar ideas. Abstract ideas about banning kids from social media or porn sites are weirdly very popular even here, mostly from people who haven't thought about what that would mean for privacy for everyone.

These ideas have become pervasive, even inside tech communities. It was so easy to blame social media and the internet for everything for years, and now lawmakers are riding that wave for political points. It's "think of the children" built on top of the current moral panics.

It's absolutely not weird. HN is the propaganda outlet for the geeks.
