Right but this was a major problem. Assange tried to weaponize the document dump. He put the encrypted dump out there and threatened that if anything happened to him the info would be released. The fact that the key then leaked is an amazing demonstration of Wikileaks' incompetence, but it does not speak to the actual intent and threat that Assange was bringin to bear against the US government.
