From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why do you think it's a lie?
Wayland could have been written to support NVidia, just as X11 does. They chose not to because they hate the driver being proprietary. Wayland had the option to be and do a lot of things that the devs refused.
False, xorg isn't written with support for Nvidia, when xwayland windows flickers on Nvidia it's an effect of xorg not working Nvidia.
The Nvidia driver is a closed source implementation of the xorg server written by Nvidia for Nvidia GPUs. Xorg was invented at a time when drivers were done like that.
Now xorg uses glamor (except on Nvidia) which is a driver that implements the server over opengl, so you don't need to implement the whole thing for every GPU. Except glamor doesn't work on Nvidia because Nvidia doesn't implement implicit sync, which is required by Linux, and that is what you see in xwayland (which uses glamor as well).
Wayland doesn't require writing a whole server, but it requires implementing GBM and implicit sync (as does everything on Linux, unless you are using Nvidia's proprietary corgi server). Nvidia refused GBM until a few years ago, and still refuses to implement implicit sync. Which is why explicit sync will solve most issues.
That was a choice made by wayland devs not too use what was available. Their fault.
What is available is a x11 server, not more not less, it cannot be used for anything other than x11. If they made X12, it would not work on Nvidia, unless they wrote a new server, which they wouldn't.
You need to understand that the xorg server everyone use literally does not work on Nvidia, because it uses implicit sync, which is required by the Linux infrastructure. The only thing that works on Nvidia it's specifically their own proprietary server.
Nvidia does a lot of impressive stuff, but they have neglected the Linux scene for a long time, because it wasn't convenient, and it shows.
Edit: ...what was available... because Nvidia is gradually implementing things the correct way, and Wayland is becoming more and more usable with every driver update. Because, surprise surprise, it does depend on the drivers. Also, both Intel and AMD work perfectly with Wayland.
