Wikipedia

It’s literally a meme how you can’t trust anything you see on there except for the most objective, undeniable facts, because you never know what page has been camped by an editor with an agenda or just a possessive streak. On anything even slightly subjective. I know there’s good editors, I know it’s a majority of them, but the problem is that the bad ones exist and so you can’t trust any given page isn’t poisoned.

Also, relatedly, the entire backend is an ever-growing morass of petty politics and tangled policies that serve mostly as a barrier to entry. They’ve been saying admin and power-editor retention is a huge problem for well over a decade, and yet they keep making it worse. At this point, the majority of their admins are from 2005, with only 10% from after 2010, because nobody bothers getting started when the prerequisites to making even a small edit can be learning the wikipedia legal system.
