This OUTDATED article gets posted all the time. The full story is the guy is a massive FreeBSD fan so he is trying to convince more people to keep on using Xorg because he wants to make sure it isn’t abandoned. Reason for that being that Wayland is built with Linux in mind and would not work under FreeBSD without a lot of effort bwing put in as it uses some Linux-specific components or libraries.
Edit: Decided to write a response because I’m tired of this ancient and incorrect article being reposted. Please read it, correct any mistakes in the comments, etc. Thank you.
