Excellent comment, I completely agree.

Anyway I want to add that Linux does not seek market share, it's an escape hatch for those of us fed up with commercial software.

Linux is used to build plenty of commercial distros like Ubuntu and rhel that do seek market share which is something their companies can worry about.

Plus, more Wayland support won't break existing X software. If you want to use old systems, don't expect new software to run on it.
