The right time for a nuanced discussion of the material published by Wikileaks was actually before the US/UK imprisoned this innocent-until-proven-guilty individual, not after putting him in soletary confinement for 5+ years. So no, not surprised. If there's need for a nuanced discussion, a course of action like this will never be the way to go about it. The time for a nuanced discussion has been over for more than ten years, and the argument was lost by the people who incarcerated him.
