Hey, even at the customer I work with now (a rather influential directorate), people have the option to choose Mac or Linux.
And: pro-tip, if you are going to work in such a place (public directorate), consider taking the Mac option because unlike with Windows PCs there are limits to how cheap the bean counters can get them and the budgets for hardware is optimised independently of the budget for hiring more people to cover for the fact that they aren't nearly as effective as they could have been and I am afraid - also the hiring budget. (The Linux option is the second best: you get the same hardware but with Linux you make the best out of it.)
That’s like one hour of the person using the machine’s time! To save them tons of frustration and wasted time from their computer thermal throttling while, say, hooked up to multiple monitors, compiling, and running a video call.
And it is getting even more widespread as most of the "office" work moves to Office365 and such which are all cloud/web based, so which OS you are running literally doesn't matter anymore.
