The media companies are absolutely paranoid and make legitimate paying consumers have a subpar experience by telling us what we can and cannot do with our own systems. The media companies believe everyone is a pirate and punishes us all with their crazy restrictions. If you don't have the correct OS and hardware and app, these media producers keep us from watching videos in HD (if lucky we may be allowed to watch at 720p) even when we have paid for the content. Keep in mind that Amazon and Netflix don't have any say in this since the rules are made by the media studios. If these distribution services want to distribute the content of the movie studios, then they must comply by the rules & restrictions of those movie studios or those movie studios won't authorize these distributors with their content. We are nothing but $$$ to the movie studios. They don't care about the consumer experience at all, it is all about control and money.
A lot of people will not subscribe to any media streaming services because of these awful restrictions and never knowing which service hosts which content. These people will only purchase content released on a physical disc like BluRay although BluRay can also force these restrictions as well if you don't have the proper TV, player, and cables (so far this has been rare for BluRay, but with each new generation of electronic devices it is getting worse).
I'm almost at the point where I will just stop watching any TV or movies from any service or even with a physical disc. There isn't much new recent content any more that is actually enjoyable anyway.
