Yeah, no.
Beyond the parental obligation arguments and regulating companies manipulating algorithms, you do have to question why so many places are choosing this particular approach to keeping kids safe. I mean it's not like kids can't access unregulated parts of the web and see far more heinous shit.
And much like other moral panics, I contend this has nothing to do with any concern for the yougins and everything to do with control. Any type of censorship regime always starts with those who can't vote against it as new justifications are found to remove even boarder categories of materials.
As far as the quality of the discourse, I've begun to suspect something more fundamental is at play- commercialization.
The early web didn't have vertically integrated billion dollar companies monopolizing most aspects of the web. Nor did it have influencers making multi-million dollar deals behind the scenes.
And that will be a much, much bigger problem to defang.
