Earlier quoted context omitted.
And how exactly is a dumb TV with no WiFi radio, ethernet port, or any other forms of outgoing communication going to phone home? Please enlighten me.
How can you prove that your TV doesn't have a WiFi antenna inside? There's plenty of space to hide something like that in.
And hell yeah you can prove it's not in there, either with a quick wireless scan or even a simple physical tear down of the housing which can then be put back together.
Show me a dumb TV that has been wired up to spy on people that has been in the wild before.
