Look I can't really go on on that. You seem to imply that this is a bad
thing. I simply say that it doesn't make sense to want this in the first
place. I don't know what to say.
But I thought that this was the plan of action, isn't it? Sign a shim that
boots Fedora. Presto, secured boot, with Microsoft's blessing.
So, did you just change your mind, and realize that:
1) It makes no sense, and
2) Microsoft is not going to sign a shim that will boot an arbitrary Linux
kernel, which can be trivially used to bypass the protection that a secured
boot offers to their non-free OS?

Yes, you're right, it does make sense. That would be considered blackmail
Somehow, I don't think they'd care how it's called, on this mailing list.
though, at least if these OEMs don't have the option to abandon
Microsoft to
sell their products to competitors. Could they even get away with it?
Who would stop them?
Anyway, this would only affect OEMs and Windows users who want to
install
their copy of Windows on machines they assemble themselves (or in any way
non-approved by Microsoft).
Which includes install into a virtual machine that did not pay the Microsoft
tax. That would include KVM.
Do we really care about them?
Well, in the same way you'd care about someone sitting on the side of the
road, all bloodied up, next to flaming, smoking wreck. You don't know them.
They're of no personal interest to you. Still, as a human being, you would
care somewhat. Maybe just a little. That's one of the things that makes you
human.
