I have to agree with you. YouTube isn't going to have much life left in it if they keep treating the content creators like they have been.
They have shut out all the smaller creators and are censoring the larger ones so now everyone is moving to DTube. Sooner are later YouTube will be a ghost site like "MySpace" is today.
I think it will be a while before that happens, but I do think it is inevitable. Though, unlike on Dtube, you can still monetize via ads on YouTube right now, and there is very little money to be made on Dtube without a major upvote, so until Dtube and Steemit begin to implement ad revenue, I think YouTube will still be the go-to!
