http://www.bbc.co.uk/news/world-us-canada-16881582 was in the news a couple of days ago. (a) To what extent do the ideals of these 'anonymous' hacktivists overlap with those of orthodox Wikipedians? (b) To what extent are they one and the same people?
I'm thinking the ideals overlap a lot. The love of anonymity and secrecy when it comes to themselves. The paradoxical hatred of anonymity and secrecy when it comes to the establishment and state and any kind of government. The obsession with hackerish things and computers. The whole 'Occupy' thing.
As to whether the people are one and the same, I don't know.
