true but next year DMCA will allow you to jailbreak PS3's.... I wonder why Sony doesn't just let it go unlike apple with ipods? :think:
I think another issue is cheating in games... Piracy is an issue, but Sony may be afraid of the backlash they would receive if a large amount of people were able to jailbreak their ps3 and then use hacks online.
Developers often considered the ones who should be responsible but they can only can do so much. They ban your consoles ID; but because jail-breaking is allowed someone has developed a method to fool the developers security protocol and get back in the game.
There is only so much the developers can do to keep their game secure; its a game of numbers and I don't believe the developers, match the numbers of those who are willing to cheat.
