But this isn't Hacktivism or whatnot. This is pure outright theft and extortion. It's not "fight the man" or "prevent censorship" or even WikiLeaks-style "information wants to be free".
It's profit-motivated organized crime syndicates trying to extract some $$ from a company. They hacked Symantec because the virus-writers of the world want to be able to write more viruses so they can infect more machines and create more botnets and send more spam and/or do more phishing...and make more money. That's it.
It's frustrating because part of the problem with a group like Anonymous is that you don't get to declare who is and who isn't a part (by definition).
I suppose human nature is human nature - in the real world or online, the same scenarios play out time and time again....
