Surprising that he had to; but David explained it well.
What happens on this board, is somehow call letters are treated as some kind of permanent identity for a radio station, especially with historical calls like KOMO, or using call letters as a brand for multiple stations or streaming. Many seem to believe that changing calls, or identifying with a slogan, means something to a listener. Newsflash: 99.9% of radio listeners are concerned about where they get what content, not call letters. You folks here are in the .1% of listeners who pay attention to call letters verses what amounts simple branding.
I don't think a case can be made that listeners jump ship from a station just because of a call letter change.
