Amazon claims it's removing Apple TV and Chromecast because they don't support Amazon Video... but Amazon was the one who decided not to support Apple TV and Chromecast in the first place.

Chromecast and Apple TV are more than popular enough to warrant app support, so it can't be a question of platform marketshare, either. (Chromecast support is so simple that the idea Amazon can't do it is laughable.) Android TV is not as popular, but Amazon already has an Android TV app, except it's restricted to Sony TVs: http://www.androidpolice.com/2015/05/16/amazon-disables-the-...

This is not a retaliation. Amazon's suggestion that this is Apple or Google's fault is simply false.

Chromecast support is not really simple, considering Amazon probably uses a different DRM system than the one Google implemented.

But for a day you could use Primecast. Amazon deliberately disabled that, so there isn't a technical reason they couldn't have resolved it.

That's what I thought it sounded like too, which made me think of the strange part - as far as I know, any Android app provider can make their video app Chromecast-compatible. It's up to the app provider, not Google. Amazon already has a Amazon Video Android app, which last I checked, they only provide over their proprietary app store. So it's up to them to make Prime Video work on Chromecast, they just have to put their Video app on the Play store, and set it up to Cast.
