The year of the Linux desktop was probably the year Microsoft introduced WSL. It'd be a non-trivial percentage of total Linux desktop users.
If you need to run both Windows and Linux for whatever reason, Windows with WSL is a better experience than Linux with WINE (or a Windows VM). WSL can run GUI apps now, too.
I'm not congratulating anyone moving to an Ubuntu derivative. They count towards Canonical's update server access stats, inflating the user count of a distributor who's hostile towards openness with their Snap stuff even if the derivative doesn't even use Snap.
