I agree with your complaint on the specific topic at hand. Whether the installed linux users are on Steam Deck or Desktop Linux, it matters not. It's a boon to the ecosystem in general and any specific differences in their distribution so minor as to be insignificant.

As to your latter point, you're just muddying the topic. Marketshare/netshare metrics are subdivided as they are because most people viewing those reports don't care what their web server, handwatch, video game console, etc use. They care what OS the computers people actually interface with runs; mostly for targeting reasons.
