I would agree but there is quite a benefit to having these smart devices connect to technology already in the home. With the absence of a proprietary radio, it's easier for me to control them as well. I currently have firewall rules on my network that blocks all communication between my smart devices and the internet. They can only communicate on the LAN and cannot send/receive information outside of the network. I feel like if more proprietary communication protocols were implemented it would be hard to determine which devices were communicating, and which are accessing the internet(for example if a device has an embedded LTE chip to make up for lack of WiFi connectivity).
