And this is why I avoid and will always avoid "Secure Boot". I can see many newer Linux people being locked out starting in Sept.
There should be some “Sane Usage” certification that a device doesn’t do secure boot, provides fully open and self-maintainable hardware, is independent of all external entities for ongoing use, provides hardware switches to turn off built-ins like ports, mics, and cameras, for power-savings and security.
"Will this piss off or delight Microsoft?" is probably a thought that goes through the heads of many OEMs when they decide how to design their machines.
Weirdly Microsoft has been one of the companies ensuring Linux remains bootable on PCs.
