If you can't even choose the OS you want to work with, it can't be a good DX. Unless their choice is what you'd have chosen anyway.
I mean not really. Linux is usually an excellent choice for development and if the rest of the company can use it there's probably no reason you can't other than maybe aesthetic ones. IMO they shouldn't take priority over creating a standard dev environment (you still need all OSes for testing, etc but that's a different point).
I have personally seen team members waste days of their time because they tried to adopt an internal script to MacOS, instead of just using Linux VM as recommended.
