What makes you think the Apple TV is any better? I'd wager that Apple collects just as much telemetry.
LG and other consumer electronics manufacturers have tiny margins compared to Apple so that extra percent or two they can make from stuff like this is pretty big for them.
Technical solutions only go so far, at some point you have to put in place a regulatory framework that requires consent. The divergences between US-EU privacy policies, configuration screens, etc. show that the GDPR is slowly starting to do its work.
People here generally don't like to hear that, but Apple is doing the very same. There's even a study-paper on how they do this without collecting personal information [0]
So when a company yells out how it's not collecting your "personal information", the statement actually doesn't cover what has been discovered here from all I can decipher from this "research"
