Actually some companies do. You want Linux since the software you are writing typically leverages a Linux environment, but the company doesn't want to support Linux so gives you a Mac machine instead. Its a poor substitute for the real thing IMO on a number of fronts at least for me. While it still works some of the time I would prefer a different environment and enjoy things like better Docker performance, avoid compile time differences between ARM and x64, odd differences in Terminal command behavior, etc, etc.
