Earlier quoted context omitted.
Give me an option to donate directly to X11 development and I am gonna support it.
Give directly to X11 development? You'll need to find someone who actually wants to work on the codebase, and then you can donate to them? No one wants to work on it.
And why wouldn't someone be happy working on X11? It is an open source project, it is high impact work. I would jump at it instantly if someone paid me a competitive wage to do it. Or honestly even a bit under my normal expectation. Not every person wants to work on some ego-driven rewrite of a rewrite. Some people are fine working with legacy code.
Also there is a counter example right above my post. Someone was so motivated to work on it, they even forked it: https://github.com/X11Libre/xserver
Granted the fork seems weirdly ideologically motivated but anyway, case in point.
