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.
What was this ad that was so objectionable?
People with actually different experiences and backgrounds, somewhat the way how the ideal model of science is set up - individual humans are fallible and partisan, get your work checked by someone who disagrees because they're the ones who most want it to not be true.
They want (woke) social liberals who look different, and at least in America wokeness is just about the most white woman thing you can do.
If you write about, say, the controversies around the Latin Mass in the Catholic Church, getting a liberal woman to check a liberal man's work is useless - they're both likely to either have a dim view of the conservative sects that prefer the Latin Mass, to be just utterly unable to understand the religious conservatives' POV and worldview, or both. I know I did until I actually befriended some, it was something you could liken to moral colorblindness - the modern secular liberal is aggressively morally colorblind and lacking in understanding of others - again, speaking from experience.
You do know that any traction you are getting with these arguments goes out the window when you start using terms like "woke".
