I think Assanges describes himself as an anarchist. He is ceratinly against power structures. As for his ethics . . . Whether you consider his Robin Hoodism ethical or not, he has done some shady things. The diplomatic cables are a different game than the corporate stuff. Some people have died. A recent article on slate asserts that he gave information to the Belarussians and used Wikileaks as a pawn in his Swedish legal fight instead of separating them as other wikileakers wished.
