except youtube is biased against the claimee and the system favours the claimer.

The most likely reason would be because otherwise, the claimer's lobby groups could put pressure on youtube to do more than it currently does (say, they can no longer claim safe habour under DMCA). The claimee are the little guys, and they while large in numbgers, have little to no power in affecting youtube's policy.

So its all down to money and economics. Therefore, a reasonable way to force youtube's hand is to make a big deal out of it, get as many people involved so that youtube feels more threatened by the actions of these small time remixers.
