Earlier quoted context omitted.
YouTube doesn't want to be demonetized by advertisers, so they are demonetizing Brand. It's basic reputation management / income stream protection. Brand is free to go elsewhere or set up his own streaming / video publishing service.
YouTube is a massive platform and inherently has power. People used the exact same argument for Twitter but I don’t think you can deny that arbitrary management choices made a huge difference in how it worked, which had substantial impacts that a private company shouldn’t have.
I continue to assert that the solution to this is not to regulate how an individual private company decides who to associate with (which is a core First Amendment right), but rather to pass strong anti-trust laws to prevent any one company from individually having enough power over society.
YouTube should be free to decide who can be on its platform however it sees fit. However, YouTube shouldn’t hold such power over us that when they arbitrarily ban someone it severely harms them.
