on the DirecTV/Boomberg News dispute, i think it came down to 2 factors for dropping the channel, and the factors are "increasing retransmission fees" and "declining viewership/ratings". DirecTV in the last 5 to 10 years have been dropping channels due to those 2 reasons combined, as they felt it's not worth keeping when the network's getting greedy and nobody's watching anyway, hence why they dropped them.
Directv removes Bloomberg News after 25 years.
Also Dish network has a dispute with AT&T SportsNet.
