Realistically, this was only a matter of time, and the Fail0verflow guys HAD to know this was coming, no matter what language they dressed it up in. You don't point out the weaknesses in a bank's security system in a public forum and then not expect to get slapped down when people start raiding the bank with what you provided.
Still, I admit, their strategy is pretty damn smart if they're not asking for damages. Logic dictates that the scare-suit, where you hit people with crazy damages, MIGHT work on a psychological level, but thanks to a lot of recent events, it's just becoming unpopular in a big way. Buuuut... demanding everything used for those purposes be turned over and then destroyed hits them in a different and more potentially acceptable way. And it actually does something, to a degree, about the root cause. One assumes that would represent a significant investment, not merely in dollars, but time and energy on the part of this group. If Sony wins, odds are they're out of the game. If Sony focuses exclusively on the guys doing the cracking, avoids asking for damages, and just basically cripples their ability to crack the system, it might be enough to dissuade future attempts.
