This is actually creating an opportunity for a reasonable competitor to show up - with Twitch deciding they are going to play "Internet police" their competitor does not actually need to be "Wild west", it simply needs to offer "We only police our service" while providing similar quality of experience.
Have a clear set of rules. And apply those equally. I don't ask much, like if you stream outright porn on platform and that is banned, maybe you should stay banned... Or if someone gets a pass everyone should get a pass...
