>"The OEMs want to make hardware that runs Windows."
I disagree. I think the OEMs want to make hardware that consumer buy. I don't think they care one bit what OS consumers run on top of their hardware. In fact I would imagine OEMS would prefer to bring their products to market without consulting Microsoft at all.
It's coercive in the sense the the secure execution is predicated on there only being one PK and the OEMs have to knuckle under to MS just to be considered a "potential" machine that Microsoft allows to run Windows.
>"Linux and other operating systems are piggybacking on the Windows PC standard."
What exactly is the "Window PC Standard"? I have never heard this term before. Linux didn't piggy back on Windows anything. Maybe you mean X86? X86 predates Windows.
