Only if you view the achievement as trying to win market share, but since Linux is FOSS there technically is no market to share with the commercially provided OSes. Market share only matters if you're trying to make money by creating the OS. Otherwise Year of Linux on the Desktop is a personal goal for the user so the usage is actually 100% when they switch over. 2021 was the year that Sally and Bob switched, 2022 will be the year Derrick, Anne and Louisa switch, etc.
Twisting the definition to a more practical idea is better for progress, and will attract more users because it will seem like a more tangible goal. And I don’t count WSL as Linux on the desktop because it was already possible to run a VM of Linux on Windows and vice versa before it existed.
Twisting the definition is acknowledging having lost the original goal.
Projects don't pivot just because it feels good doing so.
Same applies to Windows on the server room, WSL did not became a standard option despite the years of Virtual Box and VMWare just because Microsoft though it would be nice to do so.

No it doesn’t. It just acknowledges that times change, software gets better, and idea is made more accomplishable instead of betting on a single year where some sort of great migration happens (which was silly).
