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.

Maybe the field should be large enough to place a small quote/link when someone with authority to speak for the distro has said something publicly which makes their position clear.
I don't think assessment words like "hostile" should be used, unless an authority for the distro used it, and then it should be in quotes, with a link.
When you know a subject is controversial or disputed, best to use empirical facts to make your point.
