I think this says more about how the youtube algorithm works and how people want it to work.

I can't speak for everyone but at somepoint I find myself wanting to watch a sc2 game so I "turn on" wintersc's channel. Because I want starcraft. It doesn't really matter how good BAR is if I'm looking for sc2. I might want to watch BAR at some other moment, but that's a different behaviour mechanism, if you see what I mean.
