The hacker who cracked the PS3 had no respect for the intellectual property rights of Sony. Sony attempted to protect it by subpeonaing the names of those who visited the site where the stolen goods were being made available. Now those who oppose Sony taking this action of legal self-defense are assaulting the company in retaliation, executing judgment and sentence outside any real legal channel.
It is anarchist, terrorist, and the behavior of common (albeit petty, cowardly, anonymous) thugs. Punish to the fullest extent.
