You better hope that Cinnamon migrates to Wayland before Red Hat stops supporting Xorg. Despite the deeply researched and evidence based opinion above, Red Hat is the the primary contributor to many of the technologies propping up Mint. Xorg is MIT licensed of course and Red Hat has no obligation to share their changes for Xorg with Mint but they do. Most of the original software Red Hat writes is released under the GPL and used by every other distro. The very first program that Debian runs when it boots was written and is maintained by Red Hat. Fedora was founded by Red Hat to explicitly be community based and they pay the salaries of many of the prominent contributors. Regardless of what you think of Red Hat’s behaviour, I am embarrassed for anybody that honestly believes Red Hat is closed source, even without the all caps.
