There were years where, to my understanding, they were deliberately not accepting features or patches to push Wayland, which is kind of frustrating, because it misses the point of a competitive ecosystem. Like on one hand if they're deliberately sabotaging Xorg for Wayland it implies Wayland must actually be a lot better, but on the flip side if Linus had sabotaged linux in favor of seL4 we'd all be worse off, even though kernel engineers often regard microkernels as a "better architecture".
