TVs can be aggressivetring to connect to any Wifi network. Apparently some now also come with SIM cards.

My xiaomi TV is making thousands of request per day to their domains. I block them all using adguard/adblock, but imagine the amount of information they can get from a connected TV.

Samsung and LG and many others do this. Look for Automatic Content Recognition (ACR) in Samsung's privacy
