From the perspective if the people working on it, I imagine it's immensely satisfying when they successfully reverse engineer something and get it working. It's not on the same scale or of the same complexity, but I feel that satisfaction when I finally understand something I've been trying to reverse engineer in a retro game.

From a user's perspective, I can only speak for myself, but I'm grateful for the Asahi Linux project's work. I have less than zero interest in ever running macOS again. It's user-hostile, constraining, and not a good experience. I prefer Debian with Plasma 6. But Apple makes high quality hardware, and they are one of the few choices for a fast ARM laptop with excellent battery life. I avoided getting one for a long time until Asahi got to a point where it ran pretty well on the M1 and M2 with relatively few caveats. Then I bought an M1 Air second-hand, and have used it exclusively with Linux ever since. I'm very happy with it. My only complaint is that I have to waste a big chunk of disk space to keep a macOS install on a separate partition that I can never remove and occasionally need to boot into to get firmware updates since I can't get them through fwupdmgr like I can on most of my other systems.
