Yes, 30,000 videos were taken down, but how long before most of them get put back up again? I think that copyright holders are going to discover that asking Google to remove videos is a losing battle. They'd be better off joining the revolution than fighting it. The alternative is to try to sue Google out of existence, but as others have pointed out, that may also be a lost cause. For one thing, Google has plenty of cash to defend itself. Secondly, even if the content industry succeeded in suing Google out of existence, a dozen copycats will take its place, and they won't be deep pockets.
