Another way to kill smart TVs is to buy them at their heavily subsidized prices and then remove all the ad malware. Companies sell those TVs cheap and recover the costs in ads and selling your data so they will lose money.
If this trend became widespread enough to have an effect on these companies profits I would bet money the vendors would just go the legal route and crack down on it. All these LLM providers do retain logs of your sessions and these vendors would easily be able to subpoena those records. Once they start dragging people into court and mass filing cease and desist orders that's going to end it.
