We must not care about the device. We do not distribute the device -
We distribute the software. Say it is the firmware for translating
Postscript into the right commands for your printer's head - The
software is free. I can design a new printer and use that same
firmware (in original or modified form) freely, even if it is of no
use for the original device.
