If there are open wifi networks near your TV that you can’t lockdown, you’ll want to confirm it your make/model is known to automatically connect to those, and then take whatever mitigation steps are justified for your own use case.

For example, if you have multiple TVs, maybe you can swap models around based on their capabilities and location, or look up the schematic for the TV and see if it’s easy to block it’s internal antennas.

Or maybe that seems like too much of a hassle and you just say fuck it, and don’t worry about it. Which is always an option, because given how much data already gets sucked up by surveillance capitalism, my evening TV viewing habits have to be some of the lowest value data points, as I already block ads and avoid all ad supported services.
