Wikimedia is who you donate to, not Wikipedia. Wikipedia is owned by Wikimedia, and Wikimedia gives money to a lot of shady causes, laundered via the donor advised funds set up by Tides Foundation.

I say laundered because of how donor advised funds work. You donate to Wikimedia, because you hope it goes to running Wikipedia. But that Wikimedia endowment is controlled by Tides Foundation. So you can see the money go in, but not necessarily where it comes out.
