Fair. I still have a Windows VM that I keep around; looking forward to the day that I can delete it.
Amber OS.. Unchanging, fossilized, windows 7, without internet, one restore point..
you can access windows rdp from linux so there is that. i have a work machine that is w10 but i have neon. i use krdc/remina to rdp into it and everything just works.
there is vm you can do but yeah, there are options
If you don't like the tools you're given at your job, look for a better job. Having to put up with a less-than-ideal work environment is part of the job, and it's your job to evaluate the job offer and how it compares to other offers (salary, benefits, location, work quality/type of work, work environment). I use Linux at work, and have for many years, but of course not everything is ideal: I'd like to have more control over the HVAC for instance. It's not enough to make me look for a new job, though, but perhaps for some people it could be. Having to use Windows for development, however, would be a hard no for me. But for some Windows haters, other factors might be enough to make them put up with it: high salary, convenient location, etc.
