How would I require the TV itself to ask permission before sending any data beyond the Pi?
The following, which I found on their website, strongly suggests that their TVs include wifi support, see infra quote. I'm sceptical that if you didn't give your password to the TV, or someone else didn't, that it could hack you and figure it out. Of course it could be connected via *any* other open connection that its wifi can reach. Perhaps you are being sold out by a local Starbucks or Home Depot. Even if not, nothing is stopping the TV maker from putting in a 4G mobile connection so that it's always connected to *their* network, no password from you ever needed. Now you know one of the reasons why I have two tube TVs.

The first thing you want to do is verify that the TV is actually connected to your WiFi network. Does this page say it’s connected to your Wi-Fi network. If it doesn’t then the TV isn’t connected to the network yet. Go back to the network settings page, highlight your Wi-Fi network name, then press the OK button. You might have to type your Wi-Fi password again.
