One of my wife's family ancestors has a Wikipedia article. They are a reasonably famous person in their niche, multiple biographies written about them - at least one of which was cited (and clearly plagiarised in one part) in the article. There was a glaring, massive factual error in the Wikipedia article - 10 seconds with any source about him would have highlighted what the error was. They said he was X, and he was actually Y and being Y was a big part of his life. We edited it - given that every single primary source about him says he was Y (including the sources cited on the page) this should have been cut and dried. It was reverted. After a while the massive factual error was replaced with a weasel worded "there was some evidence he was Y". Someone who clearly had no clue about the historical figure was involved in small minded, petty guarding of the article under cover of "avoiding controversy" - quite possibly agenda driven to keep him in the X categorisation. I note that even though the article is now massively improved it manages to totally avoid mentioning that he was Y. If that is "working as intended" then Wikipedia is fundamentally broken and cannot be trusted for any information.
