Boss has different people for different functions within the company. A monoculture is more susceptible to systematic flaws, but it is also less expensive to maintain. It is not OPs place to decide how the company manages is computing facilities, so if WSL or Cygwin are not accepable compromises (OP and company have to both agree) then OP has to decide whether they are willing to go along with Windows or find another job.

Something to talk about during the exit interview anyway.

I think I am in the SSD camp. I absolutely hate the latest trend on MS Windows to fill the title bar with various widgets to the point where it can be hard to grab the window and move it. As with the current trend in US politics to stretch the rules well past any previous deformation, give a CSD an inch and it will eventually lead to ridiculously-adorned windows.
