In certain industries, you use what the vendors are willing to provide, or you don't stay in business. If the vendor only supports Windows, you use Windows. Period.
As an example, the plant where I work relies heavily on Allen-Bradley Rockwell Software for automation and control. There is no viable alternative on a non-Windows platform, from either a practical or a regulatory perspective. Rockwell Software barely supports 64-bit Windows. They are not likely to make any effort to run on Linux, and sure as heck won't license there software for use under Wine.
