Pewdiepie used to do a bit that covered internet drama and shit like that and apparently a lot of people liked it and liked his takes too. Problem was that wasn't kosher and he was in enough shit regarding saying the word Nigger that one time. To his credit he knows the game better than anyone and instead of complaining about how unfair Youtube is to people wanting to build a channel, he sanitized his content so it is nothing really more than reading reddit, playing Minecraft and other such games and occasionally doing a funny one off episode watching reality shows. That's all his audience really wants and that is what is keeping him safe and dry.
I wish Keem the best of luck (though I have never watched a single episode of his shit). It's an apropriate time to move on. It would have been enough an excuse to say that Youtube just isn't a platform suitable for his content anymore but instead of being delegated to something like fucking Bitchute or Odysee and screaming into the void to an audience of 800 at most, he can finally move on with his life.
