I think the most likely outcome is DD takes some time off to let things cool off, he'll return, and some people will have bailed on him, but he'll still be pretty popular... rightly or wrongly. And I say that in the most literal of terms because in these instances I think as a society we get addicted to always being on the attack, and once the alleged perpetrator of any wrongdoing has been punished(either by law or their employers or the public) people look for the next person to go after, and it'll be those who still continue to support DD and consume his content. In that regard, I don't judge. If you like his content and still want to consume it after all this plays out, by all means. It doesn't make you a bad person. And if you are put off by these allegations and no longer want to support him, that's perfectly fine as well.
I don't watch streamers so in terms of my opinions on the guy, I never had an opinion on him one way or the other. I do like to follow these gaming community stories though when they pop up, because I think the gaming community is kind of a unique entity and I'm always intrigued by how these situations from all angles are doing to play out.
