The main three things Assange/Wikileaks did that lost my assumption of good faith:

* Innuendo regarding Seth Rich (Assange clearly had no information on this subject and should have been honest about it); * Falsely presenting a leaked cable about Robert Mueller bringing a sample of uranium to Russia as part of an investigation as related to the supposed Uranium One scandal; * Privately corresponding with Donald Trump, Jr. to support the campaign and ask for favors.
