Leave FAANG and most internal developers at large corporations are running Windows. It wasn't until I started at a smaller shop that I found people regularly using Linux to do their jobs, usually in a dual-boot or with a virtual Windows install "just in case" but most never touched it.
I'm presently working supporting a .NET web app (some of which is "old .NET Framework) but my work machine runs OpenSUSE Tumbleweed. I can't see that flying at the larger shops I have previously worked at. I'll admit, that might be different -- today -- I haven't worked at a large shop in more than a decade.
