That doesn't matter now does it? How many times did the DoJ go after them? They even 'won' a few against them. None of it mattered. To this day they still charge the per PC license fees and pretty much every practice they pinkie swore to stop doing. And the Europeans haven't had any better luck.
This IS the Xboxing of the PC. Sure they allow the x86 to continue as is for now. Because they see it as a dead end. Besides, if they changed the way the desktop PC works it might anger enough people to get a legal response. Better to just make sure streaming video only plays if you haven't 'rooted' your PC, just like on tablets and phones now with Android. Then the Microsoft App Store won't work on 'rooted' PCs come Windows 9. And ever so slowly the chains slide on. And the future is a boot stamping over and over on a human face.
