Well, no problem when the customer is getting shafted, not sure the feds are necessary but somebody should be the final arbiter in the case of fraud.
The key to censorship in a free society is to somehow put a brown wrapper on the product while still making it available and at the same time, not offending those who would be offended by it's presence. Not sure how this is done in radio.
It's primarily needed for technical reasons. It's a bandwidth kind of thing. There is only so much "space" in the radio spectrum upon which broadcasts are carried. That space used to be much more restrictive, because the technology did not exist to reach the really high radio frequencies which are now common. And the technology was poor when it came to discriminating between two or more radio sources which were broadcasting very close to each other in frequency. The useable "space" is much bigger now, but the users are much more numerous.
Without government control, it would quickly become a battle of who was the loudest (wattage), and who had the best gear to "jam" the competition.

I think the key to a free and "healthy" society, is to make it unavailable. I think society has the right, and the responsiblity, to say, "if you want it, go somewhere else". That somewhere else might be a long, long ways away, and hopefully is.
