It looks like a chicken and egg problem: you don’t have commercial software available on Linux so people won’t use it, so you don’t have enough user base to justify the development of Linux versions. This won’t be solved unless a big company like Valve decides that Linux is the way and start solving basic issues like usability and installation of apps.
Funny enough, I find Gnome to be more consistent and better thought than macOS… But that’s just me.
