He's not a whistleblower (even if you think wikileaks does what it claims, he is not), he's a guy who pushed out the idealists from wikileaks so he could selectively release material to further his own agenda.
There are better places for actual whistleblowers to go. Cryptome was the better Wikileaks since forever, and it's massive shame that wikileaks took the space in the minds of the public from them. They do a much better job.
From Craig Murray's articles from the past days, it comes up that cryptome is one of the parties that released early the documents Assange is charged for, and which Wikileaks was trying to sanitize at the time. The evidence for this includes testimony from numerous journalists involved in the sanitizing effort at the time and one of the people in charge of cryptome.
You ad-hominem's do nothing to clarify the matter. Whatever your opinion of Assange may be, at the moment he's just a dude trapped in a Kafkian legal battle for not spending his remaining life in a US maximum security prison for exposing war crimes. If that doesn't deserve a little empathy, I don't know what is.
Assange founded Wikileaks. Who are the idealists you're talking about?
The most senior person to leave, Domscheit-Berg, left because he had an ideological objection to publishing information about the United States. Wikileaks was sitting on a huge trove of extremely interesting information about the US (diplomatic cables, war logs from Afghanistan and Iraq), but Domscheit-Berg wanted to focus on other countries.
Railroad whistleblowers. People in power caught out never even get the pretense of a slap on the wrist.
