It always impresses the hell out of me when I see side projects like this project that I couldn’t do myself. On the economic/$$ perspective: the Linux in M1 projects are probably targeted at Mac Minis and given that when you pay for a Mac Mini you are paying for hardware and Apple software. Does this make sense economically, comparing other bare bone systems with a Mac Mini style form factor?
Although practically I am interested in running Linux on an appleM1, my conscious will no longer allow me to fund the company producing it, so I can never own one.
