For tons of the posters here, the lot of you are acting as if your spoiled irritated children who are pissed you're not getting your way. Fact is the security breach occurred *AFTER* (repeat) *AFTER* it was initially assaulted. Its not going to be a class-action lawsuit and Sony will loose. It makes me even suspect more that it was someone just pissed off @ Sony trying to make a mute point.
If this occurred before the initial Anon assault on Sony, then yes it would be a huge liability behind it. But the fact people stole information from a security system that was already both assaulted, crippled and compromised AFTER THE FACT gives it easy reasoning that they aren't liable for it; they didn't bring the network and cause the re-allocation of resources that had caused breaches in other areas.
In that respect it is still possible to actually pursue Anon in court for the reason of interfering with the normal operations of a business and to also pursue whether they were directly or indirectly responsible. Regardless of their mo, they are, at most, still; indirectly responsible for this mess as well.
For a final point, really gamers, get off the high~horse of bashing Sony, its really moronic and stupid. I actually support the fact they went after Hotz. Why? Because its still their service and way too many homebrewers are acting like little kids because they can't brew their system to mostly play pirated games. I'M VERY SORRY SONY IS MAKING IT HARDER TO PLAY PIRATED GAMES BUT TAKE YOUR WHINING AND CRYING TO KINDERGARTEN WHERE IT BELONGS! Those posts are getting old and redundant...
