The odd machine at the microsoft.com domain is probably running Apache on Unix, and similarly for various servers at other technology companies. The web framework/OS is just a tool -- get over it.
It's also funny because of the general Apple snobbery towards all things non-apple. Which also made me chuckle because I fall into that category with my MacBook pro, ipods, iphone, and graveyard of old Apple products. =]
