I would have been more surprised if there were NO informants at Wikileaks, no organisation that relies on people is impervious to this.

What about an organization that has no secrets?

EDIT: Downvotes? Clearly I need to explain myself better. My point is that an organization built around full transparency is indeed impervious to informants. Take the government, for example. If they had made public that they'd be monitoring our Gmail conversations for our own safety, we may have agreed or disagreed with the policy but there would be nothing to leak.
