ive been watching these guys since they started... their intentions at first are completely different to what they are now... sure some of what they are doing i agree with, but go look at their twitter feed... people are boasted that they have gotten into facebook, paypal and xbox accounts (and probably many more) because of emails and password that lulzsec posted on an FTP hosting site from one of their many breaches... sure prove your point that security is not up to scratch... but dont let the users suffer because the company responsible for keeping that info secure is not up to scratch.
AntiSec could be a good thing i rate... but based on LulzSec's current POV (as well as teaming up with anonymous and any other malicious hacker wannabe that knows how to write dodgy code)... we are all gonna be effed one way or another...
