I think the problem here is that a bunch of people in these threads are pursuing different goals (those who want a non-spying TV for themselves, those who want it for their relatives, those who want the entire spying TV ecosystem destroyed), and each of them treats the other groups as if they were misplacing the goalposts from their own preferred location.

There are things like "Left: the Bible in Chinese, Right: Mozart's 40th symphony" on YouTube too, but I wouldn't take that as evidence of the existence of a significant contingent of polyglot religious split-brain multitaskers. Conversely, I do in fact know several people who run explainer videos in the background simply because they like the feeling of a reassuring voice making intellectual noises at them.
