Yeah, I understand that they've tarnished the Sony brand by exposing customer's information, but you're making it sound like they were handing out that information to anyone who asked. They didn't ask to have someone take customer information or have their online network taken down. And, I'm sorry, taking away a popular feature they no longer wanted to support isn't an invitation either. I wasn't a fan of removing OtherOS but I don't think the appropriate course of action was to steal customer information in order to defame their company.
I don't think most consumers care why they were hacked, just that their service was interrupted. Sure Sony's security sucked, but I think the general public will just hold the hackers responsible for the brunt of the problems down the road once this whole thing passes. In the end, Sony will move on and likely continue to do unpopular things which is why I don't really see anything meaningful being accomplished.
