It seems to me to be not as reasonable to think that LulzSec represents a massive amount of laziness / carelessness on the part of those admin'ing the systems, as to think that we just didn't understand the situation sufficiently clearly yet. The LulzSec twerps merely pointed out the "chaos in the universe" aka the difficulty in getting anything done.
To mangle a quote quoted in V for Vendetta (favorite subject of Anonymous): The falcon spins ever wider and soon cannot see the falconer. Mere chaos is unleashed upon the world.
LulzSec, being children, merely pointed out the chaos. To that end it's a great lesson, just like Al Quaeda / IED and the Viet Cong before that: it teaches us real people how to deal with the situation properly.
I still say fry the bastards though. Even children must be responsible. My generation could have just as easily done the kind of vandalism (and did), we just didn't want to be that big a pricks.
I actually blame the parents (the Bush-haters) for breeding such a bunch of twats as LulzSec.
Please don't mark this down as flamebait; it really is not an invalid opinion to hate LulzSec and what it stands for, no matter how much you teenagers reading this want to agree with them. Hating reality is part of teenager-hood. We understand how you feel; we all went through it.
But calling all CEOs "sociopaths" ?? Come on man, please join us back on this planet. Sure there are the Enrons of the world, and you might hate George Bush and all that, but come on guys. You've crossed the line into stupidhood now.
It ain't the security guys fault for not anticipating all the chaos that is possible in the world ;or rather it is their fault; but not due to lack of dilligence. It's just damn hard to keep that falcon flying around you :)
