There are multiple entire websites out there criticizing Wikipedia and what they have to say tends to revolve around the editing process, specifically the social/cultural aspects. Have you attempted to research this yourself?
Are you familiar with what Larry Sanger himself had to say about the bias that has emerged in Wikipedia (https://unherd.com/newsroom/wikipedia-co-founder-i-no-longer...)?
e: another comment elsewhere on this post brought up another source: https://www.tracingwoodgrains.com/p/reliable-sources-how-wik... . I've read a bit of it and can generally endorse what's being said there. In particular, some specific usernames are cited and I recognize most of them, which in itself is telling. Other comments here suggested that Sanger's personal views are less than scientific, to say the least. I have not looked into this personally, but I don't think this in any way negates the argument about bias. (Nor is any political camp immune to pseudoscience.)
