I think they're working on something as well. But just in case, MATE are experimenting with Wayland using Wayfire as the compositor, which is funny given that Compiz was very popular with GNOME 2/MATE back in the day and Wayfire is very much inspired by that.
Awesome. KDE and GNOME had the resources to make a big push and fill in the missing gaps for themselves, but having smaller, more modular desktops also tackling a port, that's really important for defining/extracting useful libraries and identifying potential shortcomings in the standards.
Most devices people use for their daily "computing" run Linux (Android) or BSD (iOS) now.
The entire backend for the Microsoft infrastructure runs on Linux.
Windows is really only still relevant on office and gaming PC's.
Android and iOS are walled gardens so they hardly count. Both are mostly proprietary these days with an "open core". When I think of Linux on the desktop, Linux for daily computing etc. I think of an experience that is interoperable, FOSS and respects my digital rights.
Well, Linux is already on the desktop. I don't know what the blog mean.
About Wayland, it still need time even if people says it's ready and blabla, I even had issues with Flatpak+Wayland so... keep on X11 to make sure all works.
I mean, there's some features now that get implemented on Wayland, which haven't been properly implemented on X11 for many years, because it was just too much pain. For example, multi-touch gestures, and I believe also automatic screen rotation for tablets.
If you are on more traditional hardware, i.e. a desktop PC, then this will not be as relevant and X11 will probably continue to work fine, for the next few years.
But it should also be said that dipping your toes into Wayland is quite easy for users on e.g. KDE or GNOME. You just install the Wayland session, if it's not already installed and then you can easily switch back and forth on the login screen.
Some time ago I switched to Wayland running Hyprland on my laptop. It basically works but I don't do much except using some web apps.
On my PC I also switched to Wayland recently, running labwc. While basic stuff works, a lot of my daily use case doesn't.
On Wayland you can barely record your screen (doesn't work for me at all with useless error message), let alone simultaneously recording multiple different windows and multiple different audio and video sources all going into different channels.
Also gaming (No Mans Sky on Steam): The Steam UI flickers like hell, and even games run extremely bad, low FPS, flickering of certain parts. Same for native games. Minetest is downright unusable due to extreme flickering of the whole window.
On X11: all of this works flawlessly and out of the box.
