Because they control the information. Can’t start such a riot if you are using their email services, social media sites, messaging platforms etc. also can’t start a riot if you don’t believe in what your rioting about, which funnily enough, they control the news and social media so you can not hear so much about that bad stuff. It’s all in the information.
That’s why I hate it when conservatives trot out that fake Voltaire quote about the ones who you can’t criticize are who rules you.
Bullshit. Kings and emperors have been satirized and mocked for millennia. It’s not that they can’t be criticized, it’s that after their nakedness is on display, the accusations fade into the dirt; nothing sticks, nothing matters.
