Factually wrong.
Any regular PC owner can run Linux on modern x86 hardware in at least three ways:
- Legacy BIOS MBR boot
- UEFI boot
- UEFI secure boot
Only the last one of those three options requires a signed shim, and only if you don’t enrol your own keys.
> Microsoft signed the Red Hat shim, and if you disabled Secure Boot, it's only because a Microsoft policy gave you the ability to disable it -- a policy they can later reverse.
This FUS has been repeated the last 10 years+ and it gets less convincing every year.
No OEM or PC vendor wants to limit their amount of potential in what is already a cut-margin business.
Taking away the ability to disable secure boot or taking away the legacy BIOS boot option will only cost them customers, and they literally have nothing to gain.
