NFL Organization review: Past practice of tv game service

I will be turning 68 years old next week and cannot understand why the NFL Organization has changed a past practice of providing NFL games through regular TV Stations like ABC, CBS, NBC, FOX and ESPN to us old Sr. Citizens who love watching professional football and now COMPELLING US to subscribe to Cable Apps like Prime and the NFL Network to watch NFL games that we might be interested in watching especially during the closing of the season and see which teams will be making the playoffs. The actions of the NFL Organization in my opinion is due to GREEDINESS! Us older Sr. Citizens who are retired cannot be affording what the NFL has implemented on us football lovers whereas before we could watch all games without having to pay an additional price range that the NFL uses to make more money with Prime, NFL Network and any other social media Apps. I've been a professional Cheesehead lover since the early 60s and am vrey disappointed as well as some other Sr. Citizen friends who've been professional football lovers. In my opinion the NFL is discriminating against Sr. Citizens
