Speaking as a professional game developer of 14 years, Windows is preferred because of two things:
1. PC Games
2. Visual Studio
Quake was developed using NEXT station (first version of QuakeEd was written in Objective-C and running on it), but since then the tools were transfered to Windows along with the game distribution. Modders could add new levels, change existing assets all on their own machines.
Windows is easy to get, easier to administer, or to say properly - not administer at all, and in the pre-internet years it was not a big deal.
Also all proper graphics cards, drivers were available first on Windows, and Microsoft somehow nailed it with D3D.
