Dr,
You must go further. The chunk of the broadcast spectrum carved out with public funds by CPB and all of it’s tentacles is enormous and valuable.
Auction off all of the bandwidth to the highest bidder who can use only non-tax exempt funds. The leftists will scream, but the concept of taxpayer-funded media is a 30 year old example of socialist creep that the proprietors consider to be an entitlement.
There is no reforming “Public Broadcasting” aside from citizens with bolt cutters, blowtorches, and creative web hacks resulting in dismantling the apparatus of propaganda.
Either that or a total legislative dismantlement.
