Well, there's no story to really address there. Barr was dangerously ignorant and naive. He had a complete misconception of how these things were organized and how they worked while claiming to know all of the identities of "the leaders" by correlating Twitter posts with what someone in IRC was talking about.

If you get on the news and say, "Hello Criminal Group. We have a bunch of information on your leaders that will get them arrested, we are meeting with the FBI next week", it is only reasonable to expect some attempted retaliation. I think that no one is surprised that the targeted group compromised HBGary's servers -- there are, after all, much worse things that could happen -- except maybe the HBGary people themselves, who, as we see here, were already in way over their heads.

No one addresses the behavior of Anonymous because it is completely and totally the expected reaction. The shocking thing about the story is Barr's personality and behavior, not the idea that someone will retaliate if you threaten to decapitate their organization.
