Rob is a very talented metal bass player and I subscribed to his videos a while ago, he has an awesome sound with his Rickenbacker Basically they have removed his bass covers of some Chilli Peppers/Black Sabbath/Sublime/Rush basically some of his favourite tunes to play. http://www.youtube.com/watch?v=9fUKPg4doUs Its a damn shame, we're not even allowed to play along to some of our favourite tunes now and put'em up, its apparently "theft".
I'm no lawyer, but wouldn't that be a violation of fair use? The only argument I can really see them making is that he's using the original artist's material in the video if he's playing along to the song(s).
