That's a function of the Secure Boot feature, but not of UEFI itself,
albeit that Secure Boot is of course a feature /of/ the UEFI. One that
can be disabled - that is to say, on x86, because one cannot disable it
on ARM - but UEFI support itself need not be included in the operating
system on x86 because UEFI on x86 does have a legacy BIOS mode. ARM
does not have that because ARM processors do not have a real mode.

Microsoft gave nothing to nobody. They are _selling_ a license key for
a one-time fee, and several distributions (such as RedHat) have
purchased such a key.

Or kernels of any kind.

If the kernel has UEFI support - and all modern kernels do - then you do
not need to enable legacy BIOS support. You can use UEFI without the
Secure Boot feature.

I agree with Linus.
