Here is a portion of the form-letter reply to my email, which says pretty much the same thing.

"In reviewing the listening habits of our audience we found that the most listened to programs on WDET were our music variety and NPR news
magazine programs. These programs have the loyalist listeners who tune
into WDET throughout the week. Other specialty programs were found to
have listeners who tended to only tune into that particular program,
creating heavy amounts of tune in and tune out during prime listening
periods. In the interest of better public service, WDET now provides
more consistent accessibility to programming so that listeners can use
it more frequently. With cohesive programming based on what the
majority of our listeners like best, WDET's audience and donor base will be fortified."

They have no idea how badly this will back-fire on them.
