I seem to recall the Journalists had an argument with Assange over the leaking. The Journalists wanted to take their time and carefully filter out any info that was not necessary such as informants identities. Assange wanted to get the stuff out as quickly as possible perhaps out of fear of being stopped before it was released.

Snowden's mistake was revealing himself. He should've done what the Panama Papers leaker did.

After the keys had already leaked, there was a disagreement whether Wikileaks should continue their plan of slowly publishing things as they went through them or dump everything since it was already in the public.

But before "the Journalists" leaked the keys, Assange was in charge of a massive undertaking to sort through the documents for responsible disclosure.
