> First, children also have a right to free speech.

Maybe I'm wrong (not reading all the regulations that are coming up) but the scope of these regulations is not to ban speech but rather to prevent people under a certain age to access a narrow subset of the websites that exist on the web. That to me looks like a significant difference.

As for your other two points, I can't really argue against those because they are obviously valid but also very hypothetical and so in that context sure, everything is possible I suppose.

That said something has to be done at some point because it's obvious that these platforms are having profound impact on society as a whole. And I don't care about the kids, I'm talking in general.
