If you don't want a TV that doesn't track your viewing habits, force automatic software updates, show ads, and do other objectionable things while claiming it's "smart", don't buy one.
Well yeah, those TVs are cheap because they use crappy panels and get subsidized by ads. If you just want a cheap panel and driver, you can message a wholesaler on panelook and buy them for like $200 plus some change for a sound bar.
A fast 4K monitor costs ~$700 because it’s a much better product.
The example of yellow tracking dots in printers has already been mentioned. Our governments had zero problems mandating the use of that specific technology. Same with kill switches in cars so that police can remotely disable your vehicle.
Maybe we could have laws that protect us from these kind of cameras instead of enforcing them. I'm against saying "No you can't do this" but I'm all for "You must show us how you do this" or "This thing must be optional".
