My impression was that the law itself was fine in this respect -- a claim could be met with a counterclaim (requiring legal commitment from the alleged offender -- signatures, identity, jurisdiction) and YouTube could then restore the media pending actual litigation. In other words, Legal Entity vs Anonymous defaults to a takedown, but Legal Entity vs Legal Entity defaults to keep up. That sounds reasonable to me, and the fact that youtube doesn't work that way is not a consequence of law but rather a corporate choice to put luxurious accommodation of large copyright holders ahead of basic decency towards content creators.

Yep. Gross.
