I dunno, Amazon keeps trying to figure out how to make Alexa echo devices profitable. Their rational was the same as their rational for AI, "we don't know currently how this will be profitable, but we are certain we will figure it out along the way".

As far as I can tell it's "buy echo devices as the 'messenger service' between all the devices we can sell for a profit (eufy/ring/etc). The thing is, no one pays much for message services (text or server services).
