Simon:
Another reason is that I doubt WikiLeaks would risk having links to Russian state sponsored hacking and be shown to be partisan.
I think you should look into Assange...
The original staff of wikileaks left because they came to believe Assange is a fascist who are in it for his own fame --- that's from Anonymous.
Remember the timeline: Assange leaked left and right about everyone up to around 2011 (I am not 100% sure about the year); he was on record saying the purpose of Wikileaks was to call out totalitarian regimes such as Putins Russia. He then reported he had a large treasure-trove of Russian information. Around that time the American banks cut off donations and wikileaks were about to go bust.
Suddenly Assange is at the embassy fleeing rape charges, and a moment later he is on RT today (Kremlin/Putin controlled propaganda outlet) IN Russia and wikileaks have no more financial problems...
After 2011 wikileaks have leaked information damaging for US/EU interests and not said a peep about Putin except some very general noises all the while leaking material believed to originate from FSB. You can find his name all over pro-Putin propaganda material and crackpottery.
This is not a far-left theory.. this is widely held by the Russian dissidents left to right, from Kasparov (by no means left; he believes Obama was one of the worst presidents and Regan the best) to Pussy Riot who, after a meeting with Assange, said he was compromised.
I know this is circumstantial but why do we know Assange is one of the good guys except he was believed to be around 2010?
