The EFF is suing Viacom over their DMCA takedown notice for a Stephen Colbert parody clip on YouTube which EFF says is non-infringing. Viacom sent out about 37 million of those puppies, based on the well known legal-analytical principle of “what the heck!”
But you’re not supposed to do that under the DMCA.
EFF has annoyed me in the past with its unfathomable selectivity about which cases to take, and which cases to ignore. (Okay, like mine.) But I have to admit, this works for me.
