A. Sony is to blame for not letting customers know sooner.
B. Both Sony and the Hacker(s) are responsible for this mess. Thus they are both at fault.
(If you really need B explained then maybe you should try hacking and secure your network to the best of your ability and ask a "Skilled" hacker to hack it.)
C. Theirs no point in all these arguments over whose fault this is. BOTH sides are at fault. You need a hacker to break into a network. You need a network to break into. The source or end result of the issue is derived from how skilled the hacker is and/or how poor the network security is.
It is interesting to see the senators and homeland security take an interest in this. Besides just the customers personal data loss, I wonder if anything was on those servers containing information related to the network and setup the U.S. Air Force has with its Sony made super computer.

As more of a personal opinion and semi off topic, All these posts repeating the same thing in altered words or the same are useless to the discussion of the thread. Someone should make an argument thread for this in the off topic so it can stop taking over every Sony thread. Posting factual information with your opinion is great. Posting something purely based on your opinion and having no relevance to the Threat Topic not so much. My 2 cents.
