As a software engineer who works on a Cloud based product, I can say that this article is true. There are already real repercussions in the industry due to this attack, but probably not as large as he makes it out to be. Many software companies are run by CEOs who don't have the first clue about security, programming, technology, etc., and have never heard of PSN.
To all the people in the comments bashing on the Cloud, realize it's just a marketing term. If you are connected to the internet, you are part of the Cloud and participate in it. By virtue of the fact you commented on this article, I must assume this true. Security is a big issue on networks. Always will be. But how many people here are saying "WHAT?? A SECURITY FLAW THAT THEY DIDN'T PATCH?? WTF??" and then turn around and say "Yeah, I never update windows. I don't like Microsoft taking over my computer and breaking things."
As far as large databases with personal information goes (the central attack point argument), do you seriously think they don't already exist? That the driver's license division in your state doesn't already have the names, SSN, and addresses of every driver in the state? That's just one example. What about credit card companies. You think they don't have all your information in a database somewhere? Of course they do. But they try to protect it. Sony clearly failed.
Like it or not, the Cloud (which as I said is just a marketing term for the Internet) is the future. It makes things easier, cheaper, faster. It's not perfect. It probably will never be perfect. Neither are physical locations. My father-in-law just had his house raided and everything was stolen, including his on-site backup. Would he still have his data if he would have made a copy in the Cloud? Yes. Banks are robbed, cars are stolen, money is lost. That's life. Try to protect your data. Choose online companies that are willing to do the same.
