Because it's likely that a lot of their equipment was actually developed for Win95/98/2000 or even DOS.

It was tongue-in-cheek, but what I meant is that most people don't upgrade their OS for fun (or for security) -- they do it only when forced by external pressure. Dunno about you, but I'd rather have nuclear submarines running on well-known and (literally) battle-tested software, screw smooth animations and glassy windows.
