Almost entirely misinformation. Saying that Xorg only used one protocol is amazing. X11 has a billion extensions. It is unusable without them.
Saying that X11 had feature parity with other desktop operating systems is delusional.
But the craziest argument is fragmentation.
Wayland is already on over 50% of Linux desktops. The two most popular desktop environments default to it. The most popular desktop environment is about to remove support for X11. The most popular desktop Linux distribution is dropping support for Xorg in October.
The only popular distro that does not default to Wayland is Mint as Cinnamon is not ready. But it too will default to Wayland within a year at most.
Even Debian Stable defaults to Wayland now.
If you want to minimize fragmentation on Linux, use Wayland.
[edit: I had not read far enough. The absolute craziest argument is “enterprise adoption”. The most successful enterprise distro is Red Hat by a country mile. Number two is SUSE. Number three is Ubuntu. Red Hat and SUSE have both stopped shipping Xorg entirely. Ubuntu is removing it in October. The idea that enterprises want us to adopt Xlibre is next level detached and deranged.]
Agreed. Also, how dense do you have to be to go on for paragraphs about fragmentation and then recommend a display server used by zero point zero one percent of Linux desktops.
