It follows the same naming convention as SFU (Windows Subsystem for Unix) [1] which was equally confusing. My belief (!!), back then, was that it was intentionally named confusing. Back when it came around, Microsoft was under scrutiny for monopoly behavior. They didn't want Windows to be compatible with Unix in any way; they wanted the world to run Windows (9x, NT) only. That was my belief/theory, as it is now I don't have anything to back it up as it is though. Your theory might equally be viable.
