Protection against identity theft should not be a privilege at the company's discretion, or a commodity if the price is right. It should be mandatory by the law, and forced until no longer necessary. (Which means, forced until PSN no longer exists.) If PSN allows for someone to break into somebody else's account, they are accountable. Not the consumer.
The PSN didn't
allow anything. http://lmgtfy.com/?q=define%3A+hacker
But if you consider the fact that not being 100% secure makes the company accountable, then you hold every website ever accountable. If it's online, it can be hacked. Microsoft, Facebook, and a bunch of other popular whatevers have had a problem with this in the past, too. (Not on as large a scale, but yeah.)
