"We’ve been trying to reach agreement with Amazon to give consumers access to each other’s products and services. But Amazon doesn’t carry Google products like Chromecast and Google Home, doesn’t make Prime Video available for Google Cast users, and last month stopped selling some of [Google-owned] Nest’s latest products. Given this lack of reciprocity, we are no longer supporting YouTube on Echo Show and FireTV."
"Users Lose as Amazon and Google Fight
There’s nothing illegal about any of this. Google can block Amazon’s products from accessing YouTube if they want to, and Amazon can refuse to sell specific products if they want to. But it sure is bad for users."
