I'm going to go out on a limb and guess that you didn't verify, even slightly, anything that tweet-thread author said.
Either that, or like the author, you agree with their claim that grant money going to journalists who are people of color is 'furthering the inescapable American culture war.'
Jeez, how dare those black people engage in journalism that isn't about white culture. They're declaring war on American (white) culture!" /s
Only if you read it in the most uncharitable way, and ignore the very real aspects of the "Culture War" around things like CRT, Anti-Racism, DEI, ESG, etc that have very real political and partisan aspects to them. Often intersecting with the very concept of what role government should play in people's life, what authority government should have, and how government should regulate both behavior and economies
I am uncomfortable with the video stills at the end that do seem to be picking on black people. Maybe I am doing the Twitter user an injustice, but there were four other grant recipients they could have been picking on as well:

Its General Counsel came from the Tides Foundation, which is as partisan as any of its equivalents on the right, and its Chief Advancement Officer, responsible for fundraising and strategic partnerships, had a long career in political philanthropy before joining Wikimedia:
The videos are what they are claimed to be. The last one features the black lady talking about how get experiments killed octopuses (weird!). You sound like you didn't watch them and are just reacting to the fact that black women are being criticized?
Its a shame so much money is being funneled to these groups since that's exactly the opposite goal of most donators to Wikipedia.
