I'm surprised that the Xmonad project is/was willing to pay someone. Does anyone know whether there was a single benefactor, or where the money was coming from, and why?

(Incidentally, I love the way that my Xmonad setup works, even though I don't know Haskell. I tried using an i3wm setup at work for maybe a year, but every evening coming back to Xmonad on my personal laptop felt like a boost of agility. I guess, if I were wealthy and wanted to move to Wayland, I would seriously consider either doing the work myself or paying someone to.)

GitHub Sponsors is where most of the money came from.
