He is a convicted criminal who used his music and status to abuse people. He didn't follow YouTube's guidelines, so they can do whatever they want. He should be happy his music is still available for streaming on YT music. And that's that. He didn't get erased from the complete internet, a company can do whatever they want. He's not entitled to a place on a platform, he should be treated just like other people who get banned/demonetized or get accounts deleted for criminal behavior.
