Your TV Is Spying On You
(www.ludlowinstitute.org)
This is a most excellent place for technology news and articles.
The article says the TVs still capture input and do recognition from external sources so using an external device is not helping.
Edit: Unless your tv is not connected to the internet.
The TV can still connect via weave, Amazon sidewalk, or other mesh networks through your neighbors doorbell or thermostat or whatever... Even if you never connect it, it could still report. Have to open it up and destroy the antennas.
