That makes it his word against the FBI, who have no comment. There aren't that many who can call in an FBI raid seizing millions of dollars worth of computer equipment causing millions of dollars worth of collateral damage to the economy. But Rupert Murdoch can. Two days ago, a pre-leak DVD copy of http://www.google.com/search?q=x+men+origins+workprint+torre.... arrived on Rupert Murdoch's desk. Rumor from a random guy on the internet alleges the Rupert Murdoch incident. When Rupert Murdoch is angry, the FBI suits up and smashes your shit. Maybe RM really leaked it and wants to make himself look less suspicious.
http://www.reddit.com/r/technology/comments/89vm4/if_you_run.... Reddit also eventually concludes that the connections here are all rumor and possibly an April Fool's joke mixed in somewhere.
I agree with you as well- that these events are likely connected, but as far as I understand it is just speculation at this point.
Also that a random guy claimed it was connected to the data center raid. Different random guys, of course.
I edited my post above to make it a little more clear, I think. Basically nothing is known about what happened except that the FBI offered to speed up their analysis of the machines if the corporations contact the FBI.
