@SuperDicq From the software freedom perspective there is no software, so there is no software to take a perspective of - there are only physical circuits.

It's a shame the hardware is proprietary, but it aight software.

ROM in chip form is quite rare now, although PROM is still popular - note that in some cases EEPROM is actually in use.


For software in things like standard microwaves, ovens and ECU's, where technically it could be updated, but in practice it never does and the manufacturer never offers updates and where such device doesn't do things like connect to the internet, the software in that case is practically equivalent to a circuit and the only question is if the circuit is malicious - but of course I do welcome free software for microwaves to make GNU/Microwave.
