- You don't have to install it because its already there
- All games just work without extra steps
- Drivers install for you without having to find them
- No need for the terminal just to make things work
- A Professional systems not a hobby project
The first point we can ignore because its a logical fallacy.
All Windows games developed for Windows work on Windows. Yes. if they aren't way too old anyway. Again this is a non point. It would be like claiming all Linux games should run on Windows. If Windows games are too old i found you have to move to WINE anyway to get ancient games working.
Drivers install for you only works if they are part of the windows hosted list of hardware and vendor is working with MS to maintain this. I have a space pilot Windows knows nothing about it, you have to go download vendor apps and install them, and change versions with windows changes. On same hardware with Linux it just picked it up as a mouse. Not perfect but better than Windows.
There have been IT update problems we had to solve from the windows CLI, because there isn't a GUI way. Don't be scared of a CLI interface it is where the real power is when you want efficiency. I run Windows and have a few CLI tools that make life easy.
As a professional I have run proprietary CAD /CAM /FEA Engineering Software on Linux as Enterprise level stuff on Desktop Linux. The gaming world isn't the only world. If you look at large manufacturers developing aerospace or automotive or transit engineering some of those invested in Linux infrastructure and there are applications that support that Product Lifecyle and its management.
