This particular attack was aimed directly at MS, it looks for a folder that is only present on some MS systems and then goes to work. So the Authors had an axe to grind with MS.

OTOH, Microsoft may just be the target of opportunity. Like the time someone asked the infamous bank robber Willie Sutton why he robbed banks - "Because that's where the money is." Why attack Microsoft? They're the OS on 90%+ of the world's computers. Who's going to write a worm to attack OS2/Warp nowadays?
