Not interesting to the people who build amateur drones for fun.

I bet that stuff like different Linux kernel schedulers, or entirely new subsystems like io_uring are written by not entirely amateurs and not completely for fun. But the ecosystem is such that open-source licensing works for such efforts. For some reasons, the same is not true for the open-source firmware or hardware used in drones.

One could contemplate on the structure of incentives that could produce a viable pool of open technologies for advanced (including non-amateur) drones.
