This is generally the purpose of the law. It's not like this is some life-or-death thing that can't be rectified. Samsung has no legal authority to disable a legally-purchased TV, and they would be sued to death if they used if for evil.
I feel like the law needs to take a greater role in this stuff. If you looted a TV you have no rights at all over it but if you purchased it legally it should be your device, and it should continue working like the day you got it outside of hardware failure which can be covered by repair and warranty.
Technical solutions will never work because the exact same feature can be used for good and bad.
