Actually, piracy is theft. Specifically, it's a form of robbery that takes place at sea. The attempt to equate the crime of copyright infringement with piracy is a gross misuse of the English language. When a ship of Somali bandits with AK47s boards your yacht, murders everyone on board (or leaves them stranded somewhere), and takes everything of value -- that's piracy. When a college student downloads warez, bittorrents "Pirates of the Carribean", or downloads the new Lady Gaga album through a P2P app -- that's copyright infringement. When the MPAA, RIAA, or BSA use the word "piracy" to describe the latter activity -- that's propaganda.
