I totally understand Sony's anger in the issue, but I doubt they have any grounds to actually do what they are proposing that they are going to do, and I'm pretty sure that they have no legal grounds to do (most) of it, though I am unsure if they might for the original poster.
I find it odd that Sony is being viewed as some mean evil company over this, with many of you speaking about boycotting the company and what not. Sony's recurring problem with people hacking their products is becoming a costly issue to the company I am sure, which is directly proportional to the livelihood of those same people who work there. I admit that I have downloaded ROMS, and I make no excuse for it and say that I am somehow justified. I fully understand that I am stealing. Anyone who attempts to justify it and say otherwise is a fool. It doesn't matter if you are a beggar in the street and Sony is a mult-billion dollar a month company, stealing is stealing.
So how can so many be so angry about a company being pissed and wanting some type of compensation from those who steal from them? I know if someone stole from me, I'd be pissed. I would be even more pissed if I poured millions and millions of dollars into development of gaming consoles, which repeatedly were hacked. This drastically reduces their profits. I especially understand their anger over their flagship system being hacked when it is still current on the market.
I'm not going to boycott Sony. I don't wish for the end of the business. Neither do I wish for anyone who ever downloaded a ROM or Jailbroke a PS3 to got to jail. It appears Sony is just pissed, and acting like it. They may even just be trying to send a message that it is pissing them off to discourage, or bring more attention to it. I'd be pissed if I were them, too, but this is not going to affect what I download.
