Why is the broadcast TV fee so high and continues to get higher? What is the endgame to this?

The broadcast TV fee continues to climb.  Most recently it climbed from $29.70 to $36.90 on my bill for basic cable.  This is a 24% increase and it now well higher than the cost of the cable service that I pay to Xfinity.  This is a charge that the networks charge cable companies for their services that they provide for free through an over the air antenna and I thought the network expenses were covered by the TV advertisements.

Is there someone in the Xfinity negotiation team who I can talk to about this or a contact from the networks who I can speak to?
