An anonymous reader shares a report: Three months ago, YouTube pulled its programming from Amazon's Echo Show device -- the first skirmish in what is apparently an ongoing war. Shortly after, Amazon stopped selling the Nest E Thermostat, Nest's Camera IQ, and the Nest Secure alarm system. Two weeks ago, Amazon got YouTube back on the Echo Show by simply directing users to the web version, a workaround that left a lot to be desired. But even that version won't be available after today. In a statement, Google said it has been trying to reach an agreement with Amazon to provide customers with access to each other's products and services. But, Google said, 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 Nest's latest products. "Given this lack of reciprocity, we are no longer supporting YouTube on Echo Show and FireTV. We hope we can reach an agreement to resolve these issues soon."
