never thought about it that way beforeThere is something with YouTube red of which nobody brainstormed before:
YouTube Red can have effect on millions of channels if people who allowed their music/games etc to be freely uploaded to YouTube and monetized as long as you don't charge for the service decide to take action. Now with YouTube Red there is CHARGE for the service, which makes all those who uploaded CC-BY-NC material in violation of their license. So now if greedy musicians claim their music, they will get rich in no time. Just a hypothesis, not believing it is going to happen.
