I call BS on anyone who claims a TV is using HDMI over Ethernet or some hidden LTE connection. When I bought my Sony TV I had no idea it was an Android TV until afterwards. I’ve never connected it to my WiFi and it’s never connected up updated itself. I can easily monitor everyone connected to my network.

Do you mean Ethernet over HDMI? Even though there was a standard and special HDMI cables that claimed compatibility, I don’t think any devices actually implemented it. Well perhaps one device according to this security paper[1] which basically means it’s useless. I control access by connecting a Samsung TV to my Ethernet network but keep it configured to use WiFi most of the time. I’ve never entered a WiFi password so the network is effectively disconnected until I configure the TV to use the wired connection. The TV prompts me to use the wired connection when I reboot my router and the link drops and comes back up but I can cancel switching to wired at that point. [1]: What the HEC?
