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.
They have strayed far far far far far from that goal
2) Who chooses which facts show up, or how do we know if certain critical facts are missing?
3) In what way are they strayed far away from it?
By introducing political bias into the selection and presentation of information.
If I check pages on feminism or even radical feminism, I wouldn't see any information on how some prominent early feminist figures advocated mass genocide of men. Most of the pages are generally shown benign.
If I check a few pages on prominent manosphere subcultures, I don't have to scroll far before the word 'misogynist' pops up, despite the fact both cultures are fairly similar (both contain a small extremist population and a large population of idealists), and feminism having far, far more text written, both per page and across Wikipedia as a whole.
Personally, I'm fairly certain spreading a few more words on the bloodlust of early feminists would shine a fairly different light on the movement without changing the ideology of the majority. It's not just information hidden away from high traffic pages, it practically doesn't exist if you don't know exactly what to look for. Yet any kind of filth is practically at the front for anything related to the countercultures. That reeks of tone setting.
