Then they are no better than those that hacked into their systems, and should be prosecuted like any criminal hacker Those that have helped them in this, should be prosecuted as accessories. Or, if what SONY is doing is acceptable, Than it was okay for those that hacked SONY to do what they did.
The law applies to all, big and small.
Keep telling yourself that as you scratch off the days, months and years on the walls of your prison cell while imagining the guffawing of Sony suits snorting cocaine off prostitutes' asses like Doogie Howser and rolling around in piles of money like Scrooge McDuck. Sony does what it likes, and if anyone disagrees they get beaten with socks filled with 100 dollar bill stacks until they shut up. Don't believe the fairy tale of equal justice under law.
