I think people are using YoutubeRed in a wrong way. You can't expect your audience to start paying, just because they watched your vids in the past. A better example are Dan & Phil. They have some YoutubeRed videos about their roadshow. You know, the thing that people had to pay for to see in the first place! So to see the full show, or behind the scene videos, you have to pay a bit as well. Putting on a show is costly, so real fans don't mind paying a bit to support them doing it. Next to this, they just keep putting out regular Youtube content like they have always been doing.
Just blatantly forcing people to suddenly start paying for something that has always been free is just stupid.
