I don’t think it’s anything so specific, but the rich and powerful most definitely want to keep social media under their control so as to keep populations under control.
Though that’s not about always preventing protests. They likely want destabilization to happen, just only in the countries they want it to happen in.
I mean if the goal was to prevent ALL protest, twitter would be boosting only happy thoughts and photos of kittens and puppies right now. But instead it’s pushing some fascist shit. Not exactly stuff that promotes stability.
