Harvard Law: "an injunction can’t shut down Grokster, the network, because it exists completely apart from Grokster, the company"
All we can say is "Bingo."
Grokster, the company, is not profiting directly from the actual infringement going on Grokster, the network, that they have created. Individuals, of their own accord, use the network to infringe. They are liable for that individually.
Grokster, the company, profits by media services associated with the heavy usage of that network. As we said in previous posts, and it appears few dispute, people install the software and use the network so heavily with the goal of infringing. Grokster finds ways to monetize this usage, and that money belongs to the copyright holders, not to Grokster. This is like suing a venue for illegally showing a movie. The venue operators may not themselves copy the movie, but the movie is the reason people came to the venue.
We don't think Grokster liability is based on the dollar amount lost by the various copyright holders based on music consumers didn't buy. Grokster's liability is based on how much money it earned selling advertising and other media services that surround the network it created.
