X11 has been, and still is, a vital piece of technology at the core of professional Unix-like workstations since decades. It has a proven track record of supporting enterprise-grade applications with long-term protocol stability and platform compatibility. It has matured over decades. XLibre is an actively developed fork of the X.Org X11 server, initiated by the most active X.Org developer and supported by the open source community.
An incompatible alternative, Wayland, is being aggressively pushed by IBM = Red Hat = Gnome = Fedora = freedesktop.org. However, it is not ready to succeed X11 as it its governance model leads to never-ending discussions and prevents even the most essential functionality from existing. Think twice before abandoning Xorg. Wayland breaks everything!
It is time that the open source community reclaims what was ours to begin with. This page lists distributions supporting XLibre so that you can make an informed choice.

I'm glad they got publicly outted for this, and the damage rolled back. These types of people are why FOSS is in the state it's in and why we will never achieve "the year of the Linux desktop" if they keep getting their way.
This is effectively why people avoid GNU/Linux. Between the fractured projects, the egotists, and the non-standardized software that seems to always be trying to replace everything, who would want to use GNU/Linux?
