NPR promotes itself as commercial-free radio. Generally, this appears to be true. They campaign several times a year for contributions from their listeners in order to keep their programs on the air. Usually I listen to Car Talk on Saturday and pick up part of Morning Edition during the week. Occasionally I have contributed to cover the cost of these programs so that I can listen to them for both information and entertainment.
Most of the sponsorship announcements are very neutral and factual. For instance, "NPR is supported by the XYZ Foundation, which specializes in educational issues." Lately, however, I have noticed that some of the sponsor announcements include some that are not factual. At least one local sponsor in particular (the Michigan Education Association) makes claims that cannot be substantiated by facts. They assert that their insurance arm, MESSA, works to keep teachers healthy so that they can prepare students for the twenty-first century. This in spite of the millions of dollars MESSA accumulates annually through these insurance policies, which help fund the MEA's political activities.
I would far prefer if the "sponsor announcements" on NPR local stations were required to be factual and non-political. It would make me far more likely to increase my own support of these stations.
