Most voices in support of Assange seem to come from people with strong conviction that he is clearly a good guy (unsurprisingly). I don’t really have an opinion. Could someone provide a more impassioned / balanced list of pros and cons? From my vague point of view, I get that he is sort of a journalist (so should be protected), but also the stuff he leaked did go quite far, like borderline-espionage scale (or is that…
Most journalists and lawyers (although not all) believe that Wikileaks' activity is journalistic, and therefore that Assange can't be prosecuted for this activity. So the US is trying to charge him for other things, e.g. for helping others hack.
Whether other states have been involved in leaking info to Wikileaks... who knows? It's likely, because, well, why wouldn't they? However no one has suggested the info released by Wikileaks is false.
As far as money, I believe most of the Wikileaks funds have come from public donations and often their legal advice is paid for by friends or pro bono. So I don't think there's anything nefarious going on there.
What has been clear is that the US will go to extreme lengths to get him into a US jail, from discussions about rendition, assassination, and faking evidence (e.g. with a key witness in this trial), to significant political pressure on allies and other states to cooperate with them on this. He is an 'enemy of the state' in their eyes.
