The judge said that the safe harbor provision of the DMCA indemnifies Google, and granted Google’s motion for summary judgement, and dismissed Viacom’s lawsuit against Google/Youtube.
My guess is the fact that Viacom was itself posting illegal material to Youtube as a pretext for the lawsuit had a lot to do with this.
I will note that the author, Greg Sandoval quoted an “expert” from the libertarian group the PFF saying that it would be overturned without noting that both litigants funded the organization.
That’s just sloppy.
