Not disagreeing with the FBI, but do _that_ many smart TVs actually have cameras in them? Most (if not all) of Samsung's current product lineup, for example. don't.
While not literally taking video and recordings of you, it's still problematic.
Tried to look for one recently without much luck. The crux of their death seems to be Skype ending support for their smart TV software. They definitely existed, though. And it was also possible to add a camera via USB in some cases.
