It sounds pretty much like they're bending the rules a bit to crack down on Jihadi propagandists on Youtube. I can't think of anything else in the modern world that can simultaneously be classified as 'online terrorism' and 'controversial religious ideology'.
I'm skeptical as to how far they might bend those rules. Especially seeing as how this is mostly being handled by an algorithm that scans for keywords.
Will it have context sensitivity? Can and will they be able to change the parameters?
It feels like the Net Neutrality argument claiming it's a good thing used to fight against something thats bad when it really means signing the internet away.
I dont trust these kinds of shifts anymore.
