I don't understand how the list of "partnerships" makes sense. None of the examples (third-party Amazon sellers, FBA, etc.) are what I would think of in terms of services I want from a home assistant, unless the goal is to order stuff from Amazon.

Neither do I understand the difficulty finding examples of Google working with other companies: Chromecast, Android, the Play Store, and Google APIs are all examples, and much more relevant to an AI assistant at that.
