I have Linux on the three machines I use. But on each it's via a VM. I run Windows and MacOS on the machines. Where I work this is common as well. It's surely pretty prevalent. The other way a lot of people work on Linux where I work is on a VM on AWS.
I don't have experience with Darwin; maybe the experience is better there.
That being said, I am very unhappy with windows 10 at work, and would much rather have some older windows version. At some point windows probably will become shitty enough that linux might seem like a viable alternative.
Lots of work places are Windows / Office effectively only. Many places have a SOE that is windows only. At home I play games sometimes. Again, that drives Windows.
Also drivers, power issues and various other issues still crop up on Linux more than Windows or MacOS.
Also, working on a VM is nice in a way because it means if it gets stuffed up, just start again quickly.
I'm typing this from an Arch instance running in VMWare Fusion on a macOS host. It's a bit annoying though -- the trackpad is emulated as a scroll wheel, making everything janky, and I can't use my host's full 32gb of RAM...
I almost never do anything but run VMWare on the host -- the only reason I haven't given back my MBP and asked work to buy me a Linux machine is because I'm waiting for the 32gb Dell XPS 13 to come out, supposedly sometime this month.
