Sling TV, PS vue and Amazon Video are three of the most popular streaming services that conspicuously do not have a tvOS app even though they support iOS. For companies that would seem to want you to stick with them on every Device you own (Like Netflix) they seem to avoid the ATV 4 like its a plague. What gives? Did Amazon and Google sign exclusive agreements with Dish and PlayStation to get first rights? Like Apple had with HBOGO?
