Because it was interesting, here's a summary: • Microsoft refuses to sign GPL3 code for secure boot, because the anti-Tivoization clause is specifically designed to prevent this (the system basically tries to achieve what Tivo did, only supporting boot authorized by people with a given key). • The Rufus developer did work to get the GPL2 ntfs-3g drivers usable in UEFI. • Microsoft appears to have no issues signing that.
