A huge number of things are terribly supported on Linux. Just as much better linux generally is for software dev, it's that same amount worse for most else. When I last tried going full linux (admittedly over five years ago), I remember wifi being a nightmare. Netflix had issues I can't remember specifically. Even ubiquitous formats like pdfs and word docs wouldn't always work correctly. More recently, I remember spotify being a pain and youtube not working as well. Maybe it's better now, but support for new mainstream products always lags in linux.

It's why so many of us try to get the best of both worlds. Dual booting with mainstream OS and linux, or ssh'ing from a mainstream OS to a machine on linux, using OSX + unix terminal, or windows + unix terminal, both options together always seems better than either option alone.

Kinda like how you could do anything in C++ that you can in Python, and vice versa. But the ecosystem is often what determines the best choice. Sticking with one and only one limits you.

to comply with company policy that only supports windows on desktops.

A lot of software (drivers, engineering suites, Visual Studio, games...) requires Windows or is better supported there or easier to work with.

Others prefer the Windows desktop, in particular for multi-screen.

Video games. Though I've finally got a second GPU and am working on passthrough from Linux to a Windows VM.

I've solved this problem to myself by having a dedicated Wintendo.
