If you follow public broadcasting around the country, there's a lot of movement in the executive director job. It's mainly a fundraising job, and requires someone to ask for money. It's harder now because the federal subsidy is gone. So a lot of EDs are going to other types of non-profit organizations.
As for WUWF, if they drop NPR, they have a lot of programming to fill. They also need to see how many members primarily subscribe to the station to get NPR news. If they can live without that money, then it doesn't matter. WSRE felt that people didn't subscribe for PBS. We'll see how that works out.
What we've seen around the country is that it's hard to replace any radio format. People who listen to radio have lots of choices. So when you change the format of something people liked for a long time, you're alienating people who may not stick around for what you do next. South Carolina Public Radio originally announced they were cutting back on NPR. Then, they changed their mind. But I don't see a change in ED as having anything to do with programming or NPR. It's all about fundraising.
