For what it's worth, Charity Navigator gives them 4 out of 4 stars with a 98.33/100 rating: https://www.charitynavigator.org/ein/200049703
Meanwhile eg the American Cancer Society gets 73/100 and spends more on fundraising than WMF's entire budget, so oncologists can snort blow off hookers in Vegas, but nobody cares.
When they flung some banner about soliciting more female contributors in my face which reeked of Americana it was the last straw.
I've seen some articles at least add “English-language criticism" by now instead of simply “criticism” when talking about the critical reception of work that wasn't even in the English language so that's a start, but too often still that doesn't happen. It's obviously unavoidable that English-language Wikipedia incurs some Anglocentric bias, but there is almost no effort to fix it and not even a template seemingly to warn that an article might carry an Anglocentric bias, even those that report on matters that mostly pertain outside of the Anglosphære.
But even scientific things. I can't read Mandarin, but I've been told many times that many subjects on many linguistic concepts on the Chinese Wikipedia look very different and that seemingly English-language linguistics and Chinese-language linguistics can come to very different conclusions from the same data. That of course is troubling in and of itself, but it should be featured proportionally.
From what I understand, among English-language communication, the Altaic language hypothesis has essentially completely bee discredited, but many linguists in Asia apparently still consider it plausible. — I don't have the expertise to judge who is wrong and who is right here, but English-language Wikipedia should either give those voices a proportional weight, or, at least note that it is discredited among English-language linguists, as right now it arouses the impression that it's globally discredited.
