The insane, continued obsession over Hillary's emails and the phrasing of the social media accounts is definitely not congruent with the clear-headed logic and essays that Assange has written in the Wikileaks manifesto, "Cypherpunks", and others.
The Wikileaks Twitter handle just used a Fox News video as evidence for something.
You could say the man's gone insane, but the theory of these accounts and the WL org being subverted by a state power sounds more plausible at this point.
