Seriously don't care about whether my analysis is insulting or not.
But you really think, that the whistleblowers were just held back, because they didn't have a website to post their stuff to?
Furthermore, if Assange wanted, he could easily spread the leaks anonymously and be quite persistent about it. That would actually preclude him or anyone else of being a martyr. Sounds like a win-win to me, unless, of course, you want either to stroke your ego or follow your own political agenda.
