Considering they recently chose to completely ignore the UN opinion on his "arbitrary detention," on top of everything else in the past - false rape accusations, ignoring his asylum status - I don't see what more he really has to lose. What are the odds he possibly gets out of this without torture, assassination, or life in prison?
They've done everything possible to turn him into an actual enemy, rather than the editor of a site facilitating responsible disclosure by whistleblowers. I wouldn't be particularly surprised if that affects the manner in which future leaks are released as well.
