There's another side to this, though. Letting kids roam the internet can give ones who might otherwise be doomed to become misfits an opportunity to find community. Being a queer kid pre-Internet, for example, sucked, and the Web rolling out to households changed a lot of kids' lives. And we have a poor cultural memory of what that experience used to be like, because, before the rise of online communities, a big part of being queer - especially being a queer kid - was being subjected to systematic erasure.
I'm not sure how you balance those two things. My sense, though, is that the balance was better 20, 25 years ago, when the Internet had more small, individualized communities. Most of them have since been squashed by the rise of the social media oligopoly.

I don't know if the downsides are worse for Facebook or Twitter (engineered for eyeballs and ad clicks), than forums, or where Discord lies on the spectrum.
