Google's referring to the fact that Amazon doesn't sell the Chromecast and Google Home, doesn't make Prime Video available to Google Cast users, and stopped selling subsidiary Nest's products last month.
Here's hoping Amazon does something similar with Google. "We hope to be able to reach an agreement and resolve these issues soon". Google has now blocked access for that version as well, and the company will soon pull support for the much more popular Fire TV, Amazon's streaming media player.
Google said in a statement, "We've been trying to reach agreement with Amazon to give consumers access to each other's products and services".
The stakes are high: many in the technology industry expect that interacting with computers by voice will become widespread, and it is unclear if Amazon, Google or another company will dominate the space.
Given the Silicon Valley rivals' status as two of the biggest companies in the world by market capitalization, its little surprise that they already compete intensely across several areas, from online search to the sale of voice-controlled products.
Now, with the feud with Google, Amazon is making its intentions known: the retail giant is making no bones about its future and plans that include a takeover of the consumer reatail space. In September 2017, after the first Amazon Echo Show / YouTube spat, Amazon ceased sales of Nest smart thermostat and associated devices, and it is notable that Amazon has never sold any Google Home hardware.
For Google, however, the loss of revenue from Amazon's website, and the minor inconvenience of Amazon apps not casting is nearly inconsequential. A couple of weeks ago, Echo Show users were told to use the web version of YouTube as a workaround, once again bringing the application back to the smart speaker.
The move was particularly to push people from Google's Chromecast to Amazon's Fire TV dongles and devices.
The latest standoff between Google and Amazon was ridiculed by a trade association of high-speed internet providers.
