I'm in design and manufacturing aerospace systems/components. And before that, design and manufacturing of laboratory instrumentation. Both were similar: options were 1) default Windows build for engineering functions and 2) default Windows build for non-engineering functions, or 3) an act of god to get something else approved. Security, monitoring, retention, I'm sure were all reasons. Also just simplifying the number of builds IT would have to accommodate.
Ive know one person who managed to get a Linux box approved. It was so they could use a particular aerodynamics software package, iirc. IT made them keep it off network and would not support it in any capacity.
Interesting.
Up till about 2018 aerospace CAD/CAM/FEA had Unigraphics/NX and PLM software as a Linux option. For who knows why, they dropped the Graphical Linux version so we are back on Windows, and headless Linux for automation only. I'm hoping with Wayland maturing they will eventually bring Linux back because it was a lot more performant than the Windows version.
