There is a chasm of difference between being misled occasionally (Wikipedia) and frequently (LLMs). I don’t think you understand how much effort goes on behind the scenes at Wikipedia. No, not everyone can edit every Wikipedia page willy-nilly. Pages for major political figures often can only be edited with an account. IPs like those of iCloud Private Relay are banned and can’t anonymously edit the most basic of pages.

Furthermore, Wikipedia was always honest about what it is from the start. They managed expectations, underpromised and overdelivered. The bozos releasing LLMs talk about them as if they created the embryo of god, and giving money to their religion will solve all your problems.
