I think you missed the point. Imagine 2 devices, device A has a chip with flash memory that contains a binary blob with firmware. Device B doesn’t have built-in flash storage so it requires the driver to load the same binary blob during boot. Both devices are reprogrammable and both contain the same closed source firmware. However device A would be allowed but device B would not. From my point of view they are the same device. The fact that you don’t know how to reprogram device A doesn’t make it more or less proprietary.
