The big problem used to be that people would buy unlocked Baofengs and accidentally use them on licensed services thinking there were generic walkie talkies. The current locked down rules prevent that. They can still get amateur handhelds and use without ham license, but hams police that. It is also easier to get FRS/GMRS handhelds for pubic use, many the same models reprogrammed.

Unlocking handhelds is less of a problem because it requires deliberate action to break the rules. There are fewer people willing and able to do that.
