The user Microsoft care about isn't running Linux. The user is running
Windows, and someone's merely using Linux as a vector to launch their
backdoored Windows kernel. How do Microsoft protect that user? They
blacklist the signature used by that Linux bootloader. If we want to
protect the user's ability to boot Linux, we need to protect the
Windows users from having Linux used against them.
