Believe it or not, there's plenty of people that specifically choose windows, not just out of fear of getting fired or inertia. The idea that all devs use a mac and that windows is garbage for any kind of development is purely a silicon valley bubble thing.
And there's still a big niche that Windows is your only choice since the move to Apple silicon. If you need both a dGPU and access to commercial software, its literally your only choice. Game dev especially comes to mind if you're jumping between maya, after effects, etc. Windows is also huge in finance.
Windows _is_ garbage for a lot of modern development (except thise targeting Win32). But that does not matter to the ICT department tasked with controlling and securing all endpoints, preferring a single, very well known and controllable OS over freedom and performance.
