It's a vicious circle. An exercise in futility that only shows that this method of DRM isn't working. Stop investing in this failed scheme and get to work on something better, Sony, if you don't want people hacking your system.
Actually, I'd say that a method of DRM that went unhacked for a good five years did a pretty good job, wouldn't you?
Put another way: A determined thief can break pretty much any lock you have on your apartment/house/whatever, just as a determined pirate can crack any DRM. But you wouldn't say that locks and home security are pointless, would you? They stop someone from just idly wandering in and walking out with your stuff. Similarly, DRM may not stop a determined pirate, but it probably does its job in dissuading some people who think "eh, cracking it is too complicated."
So no, I'd think that for this, it actually does its job pretty well.
