When comparing it to X11; it absolutely isn't. That isn't me being unfair; just objectively comparing the two to each other. Literally nothing else exists that are quite like X11 and Wayland...so it makes sense to grade one against the other.

That isn't saying it does not work as well or even better than X11 does; it just hasn't existed for long enough yet to be nearly as widely adopted as X11 is. Gnome's decision to adopt a Wayland only stance is fairly new and I'm waiting to see how that goes for them. With luck it will go well and increase the adoption of Wayland. I'm aware that plenty of Distros do include Wayland; and plenty have taken the plunge similar to Gnome; which is why they probably felt it was wise to follow suit, after observing Wayland succeeding in those Distros fairly well.

I don't really have a horse in the argument per-se; I think both X11 and Wayland are both great; if you're using them like the developers intended you to use them.

I do think the video makes a pretty good point about how people who attack others for continuing X11 is very much violating the ethos of FOSS communities in general; and I have no doubts that if the claims made in the video are true; I think folks like Stallman would be kind of upset with people behaving that way because it only harms the FOSS community as a whole.

You may not agree with people who want to use X11 for their very niche use cases. That's fine. But I do question any motives behind any kind of behavior that is not only ceasing all development on X11, but actively blocking and sabotaging others who want to work on X11 from doing so.
