>>For genuine cases, such as setting the radio strength on a wifi card, manufacturers might put that bit of the driver in ROM. If there is no cost to them, then manufacturers will DRM the entire driver (instead of just the radio strength bit), and will tell the free software community "Sorry, we're complying with regulations".
No one in the aviation business is foolish enough to put their avionics software into a ROM. FAA and other regulators require the ability to update the firmware to fix critical issues. You would never be able to ship a product as you would fail certification.
You may not realize this but ROM costs far more than FLASH based memory for large sizes. I can't think of a single device that I make or have worked on in the past three years that uses ROM for any storage.
