Not an exact fit but this sort of thing does happen https://www.cnet.com/tech/home-entertainment/samsung-smart-tvs-forcing-ads-into-video-streaming-apps/ https://www.cnet.com/tech/home-entertainment/samsung-smart-t... . Basically any ad-tech nightmare you can think of already exists... targeted advertising, telemetry reporting, replacing ads in content with different ones, etc... Currently smart TV's rely on home internet connectivity, but the current big fear is that they will start using things like Amazon Sidewalk or other 3rd party WiFi providers automatically, or even have manufacturers start embedding 4G LTE or 5G connectivity into the TV's itself so you can't isolate them without taking the thing apart and cutting out the antenna (and hoping there isn't a kill-switch if it can't call home). This has been going on for a long time - part of the reason "dumb" monitors such as digital signage displays are so much more expensive than smart TV's is that they aren't subsidised by ads and telemetry.
