To be fair, the message I got from that episode was "Alexa is a poorly designed friend replacement for lonely people", so I'm not sure Amazon really got their money's worth there.
Yeah, I saw it asa way to flesh out the anti-social nature of Dom. And I'm not sure if it's the same episode as her Alexa chats, but the scene of the lawyer's apartment going all haunted (via hack) certainly isn't a strong endorsement for smart homes.
