I am terribly sorry. If I could make Comcast take the ACCN, I would.
Everyone knew that would be the hardest nut to crack. The good news is that with everyone else on board, there has to be strong pressure on Comcast to add the ACCN. Do they really want to force customers to go to another company? Do they really want to help DirectTV, Dish, YoutubeTV, etc. steal their customers?
Maybe they will bend here. The cord cutter pressure might make a difference; that didn't exist for their earlier hard stands.
But if they held firm against the Yankees, and took 18 months to add the B1GN, the changes don't look great right now.
