Youtube are betting that we are all a bunch of spineless sheep and that we are all talk and no balls when we say that what they are doing to Youtube is a joke. They KNOW nobody will like the new channel, but they also know that very few people will actually leave over it. And, since the new layout is designed to make it easier for them to cram VEVO shit down your throat, and maximise profit, they are quite happy to lose a few users to achieve that.
