That's an interesting take on the subject. Personally, my "smart" appliances run on a closed Wi-Fi network, disconnected from the internet (the access point is a raspberry pi, which itself is connected to the rest of the network). I wouldn't trust any of these not to phone home, and everything can work offline if needs be. I tend to prefer open-source compatible solutions (such as broadlink devices with python-broadlink), but my understanding is that the Amazon ecosystem is a closed "walled garden" one. Are you confident enough in Amazon to trust that your products will continue working in the future? Are you really willing to lose your lights in case of an internet outage?
