I'm not saying that Dr. Griffin is/was a control freak, because I don't know him, nor do I know the policies of KEOM/Mesquite ISD.
I'm only talking about my experiences working in a University-run radio station several years ago.
I worked for a public radio station that changed format from NPR/APR to oldies. The station was essentially self-sufficient, and generated enough donations to pay salaries, buy equipment, etc. After the switch to oldies, the donations completely dried up, the 'advertising' revenue went away, along with the federal grant monies. The switch was made by the head of the communications department. He never gave his reasons, other than it 'was time for a switch'.
We always thought it was his personal ipod (although there weren't IPods back then). One thing that I learned about public radio.... most administrators don't even know that it is there. I'll bet that most of the Mesquite ISD school board members don't give KEOM a second thought. Odds are most in the Admin building don't even know it exists, or care it exists.
It serves a purpose. It has a format that is unique in the market, and they have some good people working for them. Would I run it a bit different? Sure. Everyone has their own ideas of what to do.
Just my $0.02
