I'd like to have all open protocols, also, but I can understand why
the vendors might not do it, on advice of lawyers and/or the FCC.
There have been some rigs on the market that you could reprogram to
operate out of spec -- outside ham bands (but what about MARS freqs?),
bad distortion, etc. Possibly you could cause the rig to fail by
changing bias levels, firmware code, or whatever. The vendors have to
prevent that or they might not get FCC type acceptance -- or they may
worry about warranty issues if rigs are getting "bricked".
If a vendor is going to provide a published, plain text user
interface, they have to do more work to sanitize it for the "hostile"
public. Many times (e.g. for typical VHF/UHF mobiles), they may
figure the demand does not warrant the effort.
Or that's my take on it FWIW.
