I remember looking at the vote history where they decided The Greyzone (one of whose journalists was called to testify at the UN on their investigative journalism) wasn’t a “credible source”, the very first vote I checked belonged to a unique username that was used on other sites for an anti-Palestinian think tank academic.
For completely uncontroversial topics it’s fine, for everything else you have to read all the dismissed/shut out outsiders complaining on the talk page to get any real sense of the topic.
Wikipedia has little legitimacy which is the purpose of an encyclopedia, I’ll never donate $1 to it and if it shut down tomorrow I wouldn’t care.
