Here in the USA, there was for many years a low-level flamewar between

Linux activists saying there's no reason completely open-source radio
stacks (for open source mobiles, software radio, etc.) would violate the
law and a coalition of (1) proprietary-software apologies (notably
Atheros people) and (2) a small but vocal group of control-freak amateur
radio ('ham') people claiming it's against FCC regulations to permit
open source.  As you probably suspected, I was in the former group.
