I think this is a good argument for the advocacy of GPL-3+ prevalence. It’s also legal, I think, to publish GPL-3 firmware source code, and to disallow custom firmware flashing, as long as the copyright is self-owned. (IIRC the provisions of the GPL don’t give legal standing for suing the author over self-violations.) In this case, would you call the software or code proprietary (which many confusingly do) or would you call the device proprietary?
