I'm not saying that I support closed-source firmware, locked bootloaders, or even that replacing SSDs is the one true path to sustainability.
I believe it's a whole field and we shouldn't tolerate compromises on any level. It should be 100% illegal in any civilized country to sell the kind of lame hardware we have today. It should be 100% repairable, 100% open bootloader & free firmware, 100% public tech docs/datasheets. Original manufacturer OS support is not insignificant, but i believe it's only significant because we have so little control/understanding of the hardware/software stack.
