In the very few areas where I am well read or even an expert, the Wiki articles I read horrify me. I consider them wholly misleading and improper. As such, I do not read Wiki articles on anything subjective (history, people, etc) because such articles of this type I am in a position to judge, I judge very poorly indeed, so I have reason to think all articles of these types are no good, at all.
For some classes of articles, such as math or computer science concepts, I find all Wiki articles utterly hopeless - the explanations only make sense to someone who already understands.
I'm conscious also of the massive propaganda efforts being exerted by various entities on various pages, such as, for example, the Ukraine War, or the Russian Government.
This leaves the balance, articles on simple, fairly non-subjective and uncontrovertial subjects, and they seem okay.
It's not great, and when I really do need to know about something, I consult an actual, curated, non-mass-edited encyclopedia.
Also, many years ago, I used to edit/contribute, but that stopped, because it became increasingly difficult and unpleasant due to other editors, and in any event, anything you added sooner or later would be removed or edited away, one way or another.
Oh and then have the Foundation, doing it's voodoo-idiocy in the background, such as the amazing new editor which no one wants or likes.
