I can't speak for LG, but my anecdata is: I own a Vizio TV. I put a wifi password on it when I first got it, but took it off later on when my TV started turning on in the middle of the night. Since then, even through a factory reset, it's somehow automatically downloaded firmware updates and installed them. They've changed how the power button worked, and other UI changes. The system menu reports no wifi set up.
