Well said. They have hardware sales at stake and want high quality therefore want to control the "openness" of their platform. I've had it with low quality PCs that fall apart in and out of warranty because they are trying to cut corners just to survive.
MS had the world or at least the fanboys convinced, that they wanted freedom of choice after people got upset at the possibility that they may not have any choices of their OS if they buy a locked Win8 PC. They saw the uproar that caused and backed down without admitting they were planning on locking PCs up. I have no doubt they will do it if they can get away with it. But the way to succeed in locking up PCs UEFI crap in place and make it very difficult to get around without appearing like they are purposely trying to lock out other OSes. Without admitting the real reason they will come up with some half baked crap about making your PC more secure and therefore since they know what's best for us and we don't, they get away with it. This is sort of like the government does things. They slip things in without asking permission and then tell half truths and divert attention long enough to let it take hold. Then there's nothing you can do but gripe about it and move on.
