Granted that it's not that difficult to protect adequately against spurious commands. However, it's very difficult (I'd say impossible) to protect a radio link against a denial-of-service attack (jamming). That alone is good enough reason to keep the command uplink frequencies, modulations, and codes as secret as you conveniently can.
