I agree, and I agree with the enthusiasm on which you bring in.

I've long since considered that the efforts for online child safety should be pointed at educating parents and spearheading some kind of certification of compliance for child safety of software and websites.

[this product is certified to adhere to EU:CSA]

Then you can block everything not certified, and the software that does the blocking would also be certified, the two major prongs you need (endpoints and sites working together: else they're blocked). The rest of the money goes to education for parents about this fact, and the dangers of not doing it, and how to do it.

This is super "easy" (when comparing to the effort it would take for putting backdoors in everything).

Which is why I think that the reason is definitely not child safety, and more about crime control.

Me talking about how its disingenuous because we have superior technical solutions to this particular issue last year: https://news.ycombinator.com/item?id=45010902
