Also, there is some incentive for the PC makers to remove the possibility to disable it: people won't be able to reuse their machines a couple releases of Windows down the road. The shorter the useful life, the more boxes they move and higher the profit they make.
Obviously, they won't think through the consequences of tying their future to Microsoft. That would require thinking beyond the next bonus window, something most managers can't.
Your wording is ridiculously deceptive. To get the sticker, they have to enable secure boot, sure. Secure boot is not an issue, as long as you can turn it off, which MS is not requiring. So no, MS is not putting pressure on OEMs to do anything remotely anti-competitive.
As for any incentive that PC makers may have for preventing secure boot's disabling, that's complete conjecture (even if it may be right in the future), so let's stick to the facts rather than FUD, ok?
True enough. They don't require manufacturers to make their computers competition-proof.
> So no, MS is not putting pressure on OEMs to do anything remotely anti-competitive.
Except that, in order to get the sticker (and to qualify to whatever incentive program Microsoft devises to go with it) manufacturers are required to make it at least very inconvenient to install anything other than the Windows that came built in. How can this be anything other than anti-competitive? A layperson can pop in a Ubuntu DVD and boot up a current PC and experiment with it. Two years from now, they won't.
PC manufacturer margins are so low any incentive will sway them. That's why every computer you buy with Windows comes with a ton of crapware - because crapware makers pay the manufacturers to do so and their low margins don't allow them to pass this offer up.
Agreed with your first sentence but not really with the second. The idea is simply securing the boot process of an operating system from POST right through to the OS being ready for use. Having 2 operating systems is perfectly fine from that point of view as long as the integrity of the boot process can be maintained. Having a boot loader and 2 or more OS's available complicates things, but doesn't make it at-odds with secure booting.
