This points towards eventually shutting out even "approved" Linux distributions. Presumably Apple can do exactly the same to prevent installation on Macs.

I"m not sure moving to ARM would help, given that the Windows Hardware
Certification requirements state:

'Disabling Secure Boot must not be possible on ARM systems.'


I don't know if this requirement will be relaxed for Windows 10, given
that it's supposed to run on the Raspberry Pi, unless the Pi won't be

I think we are still a long way off ARM desktop machines anyway. 64 bit
ARM processors are relatively new, and as far as I'm aware Ubuntu
doesn't support them (though Debian does, so it might not be too hard to
add support).
