You can receive VUDU (Walmart), Prime Video (Amazon), and YouTube/Play Movies (Google). The only thing you cannot receive is Apple's ecosystem (but no non-Apple streaming hardware can as far as I know). Same reason why Spotify is so prevalent, they too are neutral in this war between titans.
I have no sympathy for Google or Amazon in this particular situation since both have a track record of blocking out competition when they can. I do have sympathy for customers who get caught in the middle of these little disputes.
