Kids don't give a shit. Privacy is crap, they got their penis pictures on facebook. They want their fucking video games.
People playing games all day don't give a shit. They want their fucking games, stfu privacy and get moar kof33 and fucking get this shit online.
People with money to lose care. They care that their information is stolen because that could lead to their money being stolen.
People who know the value of information care. Thats few people though, since facebook exists.
In the end of the day people are willing to talk shit, when it comes to action that is a different story. How many people were so against EA's rootkits, but how many actually boycotted? Same with Apple? And now its same with Sony. Nobody will do anything. Nobody will boycott, the company will just shrug this off as an "opse".
Let's be all elitist and imply "kids" don't know the value of information, whatever that may be. More like they know the information PSN had on them didn't matter (some nickname and email). And yeah, they want they games online, that's why they paid for a PS3 and multiplayer videogames after all. And Sony promised online multiplay.
That's a badly made chain of arguments.
In this case, though, there are indications that financial data was disclosed. PSN (just like Steam and XBox Live) collects financial data to allow for online game purchases. Disclosure of that information is quite a serious matter. Yeah, the "kids" playing might not care about their PSN account, but the parents who enter credit card information to buy their kids games sure will.
A poorly made argument does not automatically render the conclusion false.
