NPR gets about 10% of it's funding from the Federal Government. It gets the "goodly chunk" from the public membership. And about another 5% from state and local governments, and public educational institutions that underwrite memberships for students etc.
The biggest single source chunk of money, and the biggest gift ever to be given a public institution by an individual, comes from the Kroc Foundation. So I guess if someone doesn't like the direction, they can dislike the majority of their fellow citizens and stop eating Big Macs, LOL
Wasn't there a satellite photo of a row of deck chairs at Area 51?
