I understand this sentiment. I am a Mac guy myself (and have been for over 10 years).

OTOH, here is how I got involved with this. I was developing a file system on OSX that I then ported to Linux. When I looked to port it to Windows I did not find any satisfying solutions and I ended up writing WinFsp.

Why port to Windows? Because it still has the biggest market share and because it was an interesting technical problem.
