By and large, your understanding is incorrect. Some stations co-op with MVPDs and provide them Internet-based feeds but most still use the old OTA reception model or are using Internet-based feeds that aren't that expensive to deliver. Providing a feed isn't a huge additional expense as they simply break out the channels before they are sent to the multiplexer and send them out on broadband or fiber (often provided by an MVPD).This does not support your assertion that the station is spending money on delivering the goods to MVPD subscribers unless you can show that the station is paying the MVPD for carriage and I think we all know that's the reverse of what's happening.
Perhaps my understanding is incorrect. It is based on information I have read here over the past 14 years. However, just saying it is wrong is not going to convince me. Do you have some trusted source you can share?
As for the second point, you assumed I was saying the cost of retransmission should always go to the station owner. That is not what I was saying. I was saying I expected there would always be a cost to deliver locals without specifying who the money would go to. I can see why you would think that as I also said retransmission fees should not be the stations primary source of revenue, but that was not my intent.
