People contacted the FCC because that is it's job. If there were no FCC, they would have called advertisers and station owners instead. Same result.
It shouldn’t be their job, that’s my point.
If you want to make the case that the FCC should even exist in the first place, you might find the constitutional justification for their existence under the commerce clause. They should regulate the signal strength of stations to ensure that business can be successfully conducted over the airwaves.
The control of content should be strictly a matter for the markets. If a station fails to deliver the content the public wants to hear, any member of the public is free to try another station. The market will develop enough stations that the majority of the people will find what they are looking for.
If you happen to be in the small minority that doesn’t agree with anything the multitude of stations are offering, you are free to throw your radio out the window and buy a book or get a hobby.
Government enforced content is the hallmark of a facist state, not a free state. And I want to live in a free state.
