Actually, you are dead wrong here. APRS is a registered trademark owned by Bob. If he says something isn't APRS, then it isn't APRS. Period.

It isn't just semantics and legalese. Bob has been very generous with allowing people to use the trademark, however he does require some interoperability. DStar's implementation does not have that interoperability, and there should not be called APRS. If DPRS were to become fully interoperable with APRS they might find themselves in a position to be blessed by Bob, but make no mistake, if Bob doesn't say it is APRS then it is not APRS.
