Has Linux desktop share been increasing lately? I'm not sure why a newer Mac with better CPU options is going to result in increasing Linux share. If anything, it's likely to be neutral or favor the Mac with it's newer/ faster CPU.

Maybe? I'm not as sold on Linux gaining a ton of ground here. I'm also not sold on the idea that the Mac as a whole is worse off interface wise than it was 10 years ago. While there are some issues, there are also places where it's significantly improved as well. Particularly if you have an iPhone and use Apple's other services.
