The case before the Supreme Court does not pertain to whether the actual act of file sharing is illegal. Let’s accept for now that when you or I grab a copy of the newest Aimee Mann track from Kazaa or LimeWire, we are committing intellectual-property piracy, stealing royalties from starving artists, and threatening the entire economic basis of the music industry. Personally, I enjoy supporting the artists I like by purchasing their records on iTunes, and I especially savor doing so after I have heard a free sample of their music over the Net. But that’s an entirely separate issue from what’s at stake in this case. MGM vs. Grokster deals with whether the creators of a technology are responsible for how it used. It’s not an understatement to say that the case could influence the future of the Internet.
