The first link is paywalled, I read the other two. Seems like those posts are evidence that there are assholes editing twitter, which I’d agree is true even without links. What I disagreed with is the idea it’s “captured” by bad actors.

I do think it’s legitimate to have a concern about people paid to edit wikipedia by malicious organizations. I don’t think Elon Musk is legitimately concerned about that; he doesn’t want an information source to exist that he can’t control.

But giving these specific examples is different than giving evidence that Wikipedia on some larger scale is no longer useful or reliable. And keep in mind here “reliable” doesn’t mean “never wrong.” I remember in school being taught that Wikipedia (like the encyclopedias that came before it) is just your first stop when learning about a subject. It’s a general overview, but to become an expert a person needs to look at additional materials.
