Microsoft has to do something about the PC pirates.

One question, though. Why should MS care? More piracy on Windows means more users locked in with their OS.

And if developers go too close to the breaking point, risking the business and thus the appeal of the ecosystem, MS can offer migration or extension to the Xbox platform where the developers make them more money. Looks like win/win to me.

If the copy protection is Windows only then it essentially means that Linux and MacOS would be completely cut out of the DRM protection/enabling chain. Only Microsoft can implement DirectX. It would help developers and probably cut off Linux and MacOS, more the former and less the latter. If they cannot run the game on Linux then they probably can't pirate it on Linux either.

It also keeps developers using DirectX APIs rather than custom APIs/languages as it would offer their I.P automatic protection as well.

Sorry but I don't understand what "only MS can implement DirectX" means. GPU drivers under Linux implement OpenGL, not DirectX, and the translation to run DirectX software is due to the WINE layer ie out of MS' control.
