The opinion raises as many questions as it solves. On the one hand, it helps address a question of fair use and internet search. To wit, copyright holders that voluntarily put stuff out on the internet (no one is forcing you to guys!) have no action for infringement when a search engine reads the material and directs people to the site anymore than I have infirnged by telling people to go look at this article on the Perfect 10 v. Google court case. OTOH, it raises serious questions about vicarious liability that, to my mind, violate the standard set forth by the Surpreme Court in Grokster.
Will need to ponder, but all my brain cells are occupied by spectrum auction.
