> The thing we want (well, that other people want, I have other views) is that large tech companies are not able to brainwash kids.

That has little connection with this law.

And having no age settings at all is where you'll have the most brainwashing.

They're already responsible for controlling that. I think they should have more tools to help.

Did you look at the law(s)? They get one of four age ranges.
