These laws are starting to appear now because for the first time AI and machine learning are making censorship at this scale economically feasible.
My guess is that a clue lies in the censorship going on much closer to home, in our own minds. Thoughts which contradict our ideas about who we are and what we should do are suppressed all the time. They fail to reach the light of consciousness. In other words, like the individual mind, it seems the hive mind must eventually develop an ego.
When i've found myself unhappy about some aspect of the broader world beyond my control, i've often been able to find the same pattern reflected in my own mindset, locally.
Matrioshka dolls:
There will be false positives and negatives. Lots.
But, this is a really good insight . Why play whack a mole when you have a mole recognition guided bazooka. No more moles.
And as usual, the people who appear to be targetted with the laws (the four digital horsemen) will figure out simple workarounds, so the laws really only harm honest people.
