I would normally agree with you but I feel like there’s a moral issue with what is essentially monetizing criminal activity. At a minimum, it should be demonetized and YouTube shouldn’t show any ads either.
Don't you think it would be better to go through a system which has (at least a semblance of) due process, fairness, and transparency about the rules? Yes yes I know I know, "they're a private company they can do what they want". I'm not wondering what they can do, more flabbergasted about the apparent sudden and large support for corporations acting to censor and punish people like this.
The solution would be for a court to take that money away at the same time as convicting him. And I think many courts would do exactly that.
Then it should be in their terms of service. In fact it probably is…
