The crew of a Panzer V facing Shermans in Normandy in 1944 might disagree with you.

You're only half right. Certainly the MAFIAA are guilty as hell, but remember that M$ have
only two arrows left in their quiver to forstall their inevitable defeat by free software:
Patents and DRM.

The 'patents' arrow is pretty flimsy, and looking at vista, it is apparent that they have
jumped onto the DRM train wholeheartedly and with both feet. After years of work on vista
they threw out almost everything that might have been revolutionary and put all their effort
into making vista indispensable for using DRM'd content.

So M$ is not just following the MAFIAA on DRM, they are fighting for survival and are
full partners in this unholy alliance.
