So Microsoft demands(!) that all x86 PCs and laptops which are sold in its certification program have to have Secure Boot easily disable-able in the BIOS/uEFI by the end user...
So these Linux-computer companies either buy laptops from manufacturers directly or produce their own, but somehow the laptops they're buying are unable to have Secure Boot turned off even though that is the industry standard and literally what every single laptop retailer's laptops do?
This whole thing makes no logical sense at all.
I totally doubt that anyone is producing x86 laptops where you cannot disable Secure Boot, if for no other reason that it would make these laptops ineligible for Windows/Microsoft certification which consumers care about.
These companies might be going out of business, but trying to tie it to Secure Boot is nonsensical.
Plus on top of everything I just said several Linux distributions now support Secure Boot out of the box. So these companies don't even have to go into the BIOS/uEFI and change the settings, just install Ubuntu like they always have.
So OP: PROVE that Secure Boot is the cause of these companies going under? Or at least explain the logic to it.
