It's notable that this release has nearly ZERO attempt to market to or engage with 3rd party developers. It is solely for 1st party apps, solely under their control. Google picked a consumer device with extremely limited, contained functionality to target Fuchsia to.

This is an extremely crazy twist for a device that is supposed to play a star, core role in the home, and a strong indicator to me of where we are in the War Against General Purpose Computing.

There are definitely ways for 3rd parties to add to the experience, with the chatbot platform, but it's all expressed in Google's existing mold, via Actions with Google Assistant & other pre-baked systems of manipulation.
