I don't think I've ever seen anyone seriously defend what Anon did in the more detestable cases. As You Know
, Anon is neither omnibenevolent nor omnimalevolent, much like humanity as a whole. It just is. And while there's not exactly much you can do to influence the behavior of an amorphous superconsciousness, positive reinforcement for the good things it does do seems like a worthwhile effort.
You make a good point, but at the same time, HBGary was, to an extent, defrauding the US government. I have no sympathy for them. The workers, yes. If they're fired, they'll have been caught up in unfortunate events beyond their control. However, just as an example of something similar, take the Enron scandal. They collapsed due to corruption, and their workers were out of a job. Job loss is an inevitable consequence. As to whether the innocent workers ought to be compensated for their losses if they are indeed laid off because of this, however, I'm ambivalent.
