I find it more surprising that the common understanding has shifted away from "wikis are crap for anything new or political".

As soon as there is a plausible agenda for selecting a narrative the way Wikipedia works we should be sceptical.

For recent examples, everything to do with Biden and family, and Gamergate. These pages are still full of discussion; and what's written is more ideological than factual. You can follow these pages to see how an in-group selects a narrative.

And these topics are not nearly as controversial as race, feminism, or transgender topics.
