> For one thing, it's kind of the reverse: it's telling Apple and Google to get their shit together and not degrade performance of Prime Video on their devices (last I heard, my Apple loving family still couldn't watch Prime Video).

Apple doesn't make apps for the vendors, the vendors make apps for the platform. HBO and Showtime created apps for Apple TV. Amazon is deciding to not create apps on Apple TV and Chromecase, not the other way around.
