The DMCA sucks but it could be worse. Unfortunately, for those guys trying to make a living off of making Youtube video's, it can be quite neabulous whether their content infringes on anything. They can often be caught with an invalid DMCA takedown notice which removes all earnings from the video until the DMCA claim has been removed. I know that AngryJoe has had his ass bitten more than once, and I would hardly consider his content to be infringing.
