"by ending the sale of devices from Google Inc. and Apple Inc. that aren’t easily compatible with Amazon’s video service." I predict they'll make it easier soon. Amazon is pulling an "easier to ask forgiveness than permission" approach to negotiations.
Aside from "Amazon said it in a press release", is there any reason to think that these services really aren't "easily compatible with Amazon's video service"?
I mean, lots of other video services support Chromecast and AppleTV, and I haven't heard of it being particularly difficult.
