It's an approach that is entirely consistent with the shit stance on these matters that Assange/Wikileaks have taken for years. I ranted about it some years ago more effectively than I am able to repeat now, because I had suitable quotes from an Assange interview or two with a business magazine or newspaper and I don't have any of this detail to hand now.
From what I recall it seemed fairly clear at the time that he saw it as his right to harness whatever power and profit from the information, the timing of its release or its non-release, etc, as he could. He wasn't subtle about this at all and it seemed easy to find heaps of hypocrisy and contradiction at every turn.
