If Microsoft will revoke keys for whatever reason they want, without
any regard to the potential PR and legal consequences to Microsoft,
there's absolutely **nothing** you can do, short of choosing to use
more open hardware (for example, like the Chromebook Pixel).

If you're that terrified of the completely arbitrary and capricious
Microsoft guy having us by the short hairs, why aid and abet Microsoft
control-freak model?
