On the other hand, blocking absolutely adequate YouTube accounts (engineering, education, history) without explanation and appeal process is super unethical. Creating monopoly (which definition YouTube perfectly fits) is not only unethical, but against the law, as well as constant user's privacy violations.
Some content creators on YT (such as Legal Eagle, etc.) are also now on Nebula. $15 USD per year right now. Apparently they don't have to worry so much about de-monetization, however that works.
Being the dominant player in the market doesn't make it illegal. It has to either have reached the dominant status through illegal means or engage in activities that help it maintain the position by destroying competition using anti-competitive means. What did youtube do to be "against the law"?
