Blocking something is very different than looking up what they click. After 12-14 it can very well get dystopian in my opinion. Kids have and need to have secrets from their parents at that point.

You also don't want moral busybodies at school make mountains out of molehills to make it more traumatic than the content they perhaps consumed and wasn't age appropriate. A while ago parents were oblivious to what content their children consume and didn't even have blocks. The children survived too although a bit more engagement might indeed be sensible.

As I said, it was criticism of surveillance, not blocking content or in general curating content for very young children.
