When should we require that firmware be free?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It doesn't make any sense. If I make a box with a screen that runs linux (idk for ordering lunch in school canteen) and only update the OS by physically removing the hard drive and installing it from different computer, does that justify it being proprietary?
On the other end a circuit can be changed e.g. by tuning a potentiometer or straight up changing a component. That's not any different than changing a value of a variable in the firmware. There is no actual difference in hardware and software, just different level of abstraction like C vs Python.
