From what I heard last, Wikileaks had a leak of their Twitter PMs, supposedly, and some of them were quite on the far right spectrum of "that's not nice". WL has neither denied nor otherwise objected to these claims and leaks to my knowledge and there wasn't any evidence they were falsified as far as I was able to tell. IIRC the founder also promised to hand himself over if Chelsea Manning was pardoned, which happened at some point and yet he remained hold up in there.

I think WL at some point was "the most powerful force bringing to light information the public should know" but it's no longer the case. They just dump data into the internet with no sense of moderation or actual journalism.

Dumping a lot of data isn't journalism. Everyone can do that. Journalism is processing and summarizing the data, pointing out the parts that are troubling.
