If you turned on your Amazon FireTV and loaded up the YouTube app you would get a notice that the app will stop working starting January 1, 2018. YouTube is of course the world's largest video sharing site as well as the world's most popular on-demand video service. So not having it supported on a steaming device is a big deal. Google has said their decision to pull it from Amazon devices was in response to Amazon hampering sales of Google products.
