The biggest problem I see is this big push into proprietary digital modes is that it creates incompatibility. These digital modes splits the market up into incompatible segments that damages the ability to communicate. This splintering reduces the desirability of a new radio, and reduces sales. Reduced sales means vendors spend less on R&D. Who wants to buy a digital radio that can only communicate with a small fraction of other digital radios? I've talked to dozens of hams, and their most hated feature is accidentally entering digital mode on their radio and not being able to communicate with anyone. Similarly the majority of repeaters are analog only, because who wants to put up a repeater that only a small fraction of the radios can use? If the FCC required only open systems being used then any radio could use open software to be able to communicate and help ham radio become a more modern radio system.
