And then some Linux distributions set out to fully support Secure Boot (Red Hat, Ubuntu, SUSE, to name a few). This was accomplished by these particular companies purchasing digital key that would then allow their bootloaders to pass the UEFI firmware check. With that, those distributions have no problems dealing with Secure Boot.
