Amazon prime video airplay blocked on all Apple devices, why?

Why is it that Apple cannot figure out how to come to an agreement with the largest online book and video supplier in regards to making apple airplay available for Amazon prime video account holders. Amazon Prime is a pretty cool technology but politics and money are blocking Apple users from being able to use this technology. You can hear the movie but there is no picture. Nothing is wrong, Amazon has just blocked all Apple users from what I can tell. It does seem a bit hush,hush for some reason. I love Apple, but they need to learn to play with others better or they will find themselves in decline with all the Microsoft tablet products out there. Anyone wish to weigh in on this dilemma?
