You are by far the angriest person I've seen about this issue, more so than people I've watched get hit with actual fraudulent charges.
Yes, Sony fucked up big-time. This is being considered one of the top-5 worst data leaks (or whatever you want to call it) in our history. This is a PR nightmare, and the PlayStation brand will suffer as a result. They're facing an uphill battle with looming lawsuits, round-the-clock updates to their datacenter (in both updating the servers and their security, as well as physically moving the servers to a more secure location), and a campaign to convince people that the PlayStation brand is still any good, since the NGP is on the horizon, the PS3 still has years of life left, and the PlayStation Suite has been implemented in a number of devices such as the Xperia Play, which is mostly useless now due to the PSN outage (Suite, not the phone). It's 2011, and one of the biggest electronics companies in the world should not be this far behind in their knowledge of software securities. People have been affected by this, though Bloomberg, an legitimate organization dedicated to business-related news, plainly states that Wells Fargo, American Express, and MasterCard have not seen any unauthorized activity related to Sony. These people have to now go out of their way to get new cards, change passwords, and all sorts of precautions, in order to play it safe (though, this is definitely one good thing to come out of this: people get to take a good look at their own personal security).
With all of this information in the public eye, there is literally no amount of money that Sony could spend that would spin anything in any other way. You know that. They know that. They're trying their best to save face, and it's nice to see Sony is actually finally admitting they screwed up instead of pulling an Apple with the iPhone 4's antenna issue, but in the end, they know there's a lot of work to do that will never fully undo the damage done.
Yeah, Sony definitely shot themselves in the foot, face, and crotch with this one, but they did not kill your parents, your friends, and your pets. They are not the only big company out there with security this bad, I can guarantee you that; they just happened to get caught with it in the worst possible way. Sony is not the heart of evil. They're a company that did something incredibly dumb that potentially cost some innocent people money, which is never okay. My information was up on PSN as well, but you don't see me throwing chairs over it. I changed my shared passwords (something I should be doing anyway) and use only PSN cards (I have an old debit card up there that's since expired, so whatever). I took precautions, and I'll wait and see. If something happens, I'll talk to Visa and my bank. If nothing happens, what do I care? Should I write yet another angry e-mail to Sony? There's nothing I can do that hasn't already been done and will make the situation better or worse. After all, there are people who have been affected by this who plan on jumping on Portal 2 and getting The 3rd Birthday the moment PSN goes back up; that's pretty telling, I think, in one way or another.
Just calm down a little bit. This is not worth raising your blood pressure over.
