content: I seriously hope that this demand prevents computer manufacturers from disabling the ability to turn off secure boot with the latest UEFI standard update.  If you have to go through secure boot, you're going to have a difficult time, at best, booting any Linux kernel that isn't signed by Microsoft, and you'll probably have a much nastier time of things with more niche operating systems (I don't see Plan 9 getting an officially signed kernel any time soon).  Plus IIRC, properly signed Linux kernels may be unable to load unsigned modules, which may cause even  more problems.
