I thought the Twitter thread that was on HN about how Wikimedia sends money to other charities was interesting. The tl;dr is that they regift a lot of their donations to charities and advocacy organizations with limited effectiveness. The post got flagged off the front page, maybe because of the tone of the person who wrote it, but I thought the objective facts they shared are still worth knowing.
If Wikipedia has enough money to fund youtubers who deny the scientific method, I'm a lot less inspired to donate.
