It's fallen into the memory hole. See the current Wikipedia page, no mention of Assange's ideologies from teenage years all the way through founding WikiLeaks. And also no information doing simple internet searches. I'm not motivated to try digging deeper, because, well...not worth the effort.

IIRC (...and maybe I don't) it was easy to run across allegations (which seemed to make sense) of his ideological leanings...I think related to hangers-on of the cult his mother got the family involved in.

That and his frequent appearances on Russian media at the time (8+ years ago). People forget, and however it happens, information falls into the memory hole.
