Ever notice how there are no cookie popup on sites like Wikipedia? Funny how you don’t need it unless you’re being a total dick with the users data.
Wikipedia is a not for profit with 250 million in the bank, so its got other fund raising going than ads. I would say it giant donation prompt that covers the top 1/3rd of a page is its own dark pattern, they just do it internally.
For a contrasting for profit wiki, go check out Fandom, which is owned by Wikipedia’s Jimmy Wales. It’s full of cookies, enshittification and dark patterns.
