As much as I hate to see the lack of classical music stations, or the downfall of said stations, the Libertarian in me decries the use of public funds to support things that the public wouldn't support on their own.
If a station can't produce interesting, good classical music, in a format that is appealing, and interesting enough to generate enough advertising dollars, then it really has no business to exist. As much as I love classical music, even I wouldn't argue for spending tax dollars to support one musical format over a different musical format. I mean, if KRAP - a 24 hour rap station were faltering, and couldn't afford to pay their bills, would you expect a gov't handout? I think not.
