remember that we also have flaws at the hardware level, namely the firmware
we don't know what they do now inside the firmware
in fact I would prefer to use old devices with secure firmware, like old thinkpads in practice, with linux obviously
Well, in that case we should have some type of hardware that should be open source at firmware level. I believe RISC-V is something that could play some important role in life of privacy enthusiasts. However, I don't
know if it's possible to have open source level firmware on RISC-V but as far as I know the processor architecture is open source, but again someone themselves won't be able to create a processor out of it, that's also going to be created by a company but if the company makes firmware of it open source then that's going to be much helpful.
