It's not just "DNC and US intelligence." Wikileaks tried to influence the 2017 election in France among other examples. See https://fr.wikipedia.org/wiki/MacronLeaks. This partially backfired when the dump of e-mails they published was found to contain russian-language messages.
That Wikileaks systematically favors the russian government, and never does anything contrary to the interests of the russian government, strongly suggests they are an asset of russia.
Tell me and be honest: is that link to a politically-motivated, unproven allegation that will be believable only to those who want to believe, because the "evidence" will be a rabbit warren of innuendo, emotionalism, question begging, circular citations, and talking head pundits assuring us all that they have seen the evidence and "it's extremely credible"? Because that's all the anti-Assange people have so far.
Exposing corruption mainly in the anglosphere is not some systematic error if that is what you do best and where most of tge organisation live and know people.
You could claim Wikileaks is a Thai or South African asset too on those preconditions.
