I'm surprised a company the size of Sony with all their resources were unable to prevent hackers getting in!
I would have thought their security would have been second to none, so either it was crap or the hackers were exceptionally good.
I never understand why people with such exceptional "talents" use them for all the wrong reasons but then again, using them for criminal gain is that much more profitable. 
Soo glad I'm not an online console gamer! 
Sony aren't interested in protecting its customers. Never were in recent years. They are interested in how to provide a set specification for a minimum cost price, and trade on their (supposedly) good name to charge premium prices.
The same applies to the gayStation Network. Build something that (almost) does the job for the lowest price possible, and run it on a shoestring. Security? Nah, too expensive.
Then, as a matter of greed, reduce the advertised functionality of the console, then try to use the law to stop people who do provide methods to re-enable that promised functionality... ...now I'm just the stupid kid from the local comprehensive, but even I can see that will enrage some very talented people. If they couldn't see that coming given the last couple of months happenenings, then they really do, as I suspect, have their heads so far up their own backsides.
All large companies put shareholders before customers, its just Fony are particularly bad, yet have a local following of sheep, who will only ever consider Fony, and not even look at other manufacturers (though they will claim they do). I will forward Martin Imber as a case point here

. Same with BMW and with Apple - they will both also overcharge customers and under deliver, yet their customers wouldn't dare look elsewhere

The company everybody loves to hate, Microsoft, understands security and how to provide a service, hence the XBL service remains the most stable. Possibly because they know they dont have a loyal following like Fony/BMW/Apple/etc, they treat their customers with the respect they deserve. Quite unusual for such a large organisation.
