Given all the upvotes on this post, I'm guessing I'm in the minority. But, I'm not a fan of wikileaks' ethics. Whistler blowers are important, and I have a lot of respect for their bravery, but wikileaks feels like a metalayer on top of whistle blowing that feels slightly gamey and a little celebratory.
It's rather unavoidable to venture a bit into self-righteousness or vanity when you voluntarily act on ideals. If wikileaks somehow maneuvered into to being the only repository for whistle-blowers, then certainly, their pride would do their a mission a grave disservice. Still, whistle-blowers find few places of refuge these days, and wikileaks has demonstrated substantial effectiveness in being just that. Actively protecting/encouraging whistle-blowers out of idealism, while also acknowledging the consequences of vigilantes pursuing such ideals (collecting too many eggs in too few baskets), need not be mutually exclusive. It's a zero-sum game, otherwise.
