A tiny niche that's only accessible to people who know how the internet works. Ask your regular Joe if they've even ever heard of the Fediverse. Kids will flock to the easiest accessible and largest platforms. Not Lemmy. And even Lemmy would be toxic for kids.

Its not really something kids can do though. The overwhelming majority of parents neither. Hell, I consider myself somewhat tech savvy, but I'm just starting on that journey.

I have no idea what a good regulation might look like, but just letting techbros do whatever they want is not an option.
