I don't see it now but I could have sworn he said that the climate change article should have more information on how it is contested. Personally, I don't think that's reasonable because it wouldn't accurately summarize the state of knowledge and reputable sources around the subject.
I chafe as much as anyone about overly propagandist texts in Wikipedia (and I've deleted or edited a fair few) but the climate change article seems overall fine. It's not slanted or anything. I'm sure one could interpret "intellectual diversity" to include outright nonsense but I don't think there's much point to it. In any case, considering he has the Citizendium project and has only sporadically contributed to Wikipedia over the last two decades, I don't get why he's back here.
For some reason, back in 2025 he decided to archive his previous user page describing his resignation in 2002[1] and start this Wikiproject and do not much else.
I don't know, man. At some point, one no longer retains any authority as founder. The whole thing just seems like some kind of culture war nonsense.

Wikipedia is perfectly happy to promote the grand narrative that they are the thankless sacred keepers of humanity's knowledge. They'll take your edits. And they are perfectly happy to take your money for this divine goal. Just take a look at the marketing they plaster onto every page during the fundraising drive.
But the second that someone commits the grave sin of "canvassing" outside of Wikipedia to bring attention to an issue they care about, they get banned, and the discussion is ended. There's just a total lack of accountability for anything unless you play by the thick codex of online governance rules they made up.
It's why I haven't ever donated anything to Wikipedia.
Interpretations of complex webs of facts often diverge along tribal lines and bias can easily leak through when editors need to decide which interpretations are authoritative.
But if it really wants to be a community build site, it makes sense that a Co-Founder doesn't have any special rights. ("The irony is that not even a co-founder can edit it if he is attempting to implement his program of reform.")
Few people can acknowledge or even realize that there are hundreds of Wikipedias. Mostly language-based, but some are language-neutral.
But they all boast their own unique communities and unique internal rules. Never judge WMF based on enwiki alone!
