well, the scary thing that KPBS does NOT sell ads. It is a NPR-affiliated station, which lives off donation of its members (http://www.kpbs.org/default_members.php). In fact, NPR is the closest thing we have to a non-corporate radio. And that's exactly why it is sad when they fail in their responsibility to educate the public.
Or, are we already living in an Corpo-Orwellian world, where even "independent" institutions, like universities and public radio are controlled by business interests?
