While low power transmitters, 100mW or so, are generally not dangerous, and thus should be deregulated in the VHF/UHF ham bands, so that the general public can use spectrum it legitimately owns. The "listen before talk" principle should be required by the regulations, and thus implemented in firmware. And even if misused and hacked to transmit on emergency frequencies, the harm a low power transmitter can cause is still limited.
In the end it comes down to if the industry and general public is a more powerful lobbyist than the amateur radio community, which is tiny by comparison. Who has more political power. And I think the general public might be the one with more political power here, and rightfully get to make the decision?
The radio spectrum is a shared space. In a democratic country, a small minority should not be dictating the rules for the majority here?
