I doubt anybody involved in targeting and suppressing Wikileaks post-2016 is leaking their plans to Wikileaks itself.
There's no reason whatsoever to assume WL has any information about anything at any given time, unless they've publicly suggested that they have.
this is not clear. A sufficiently small organization needn't have whistleblowers. The extreme level of confidentially practiced in the relevant organizations ensures that the number of people privy to the knowledge and capable of leaking is very small.
