Note that the LG takes regular screenshots, uploads them to their servers, and sells them. If you don't allow it on the internet, it saves the screenshots to internal storage and uploads once it is connected. If you don't attach it to the internet, or give it permission to upload them, and later sell the screen to someone who does do that, all your data is uploaded then.
I would not resell a LG tv that has been used for anything but content consumption.
That’s a rather outrageous claim! Do you have evidence for this?
Is it perhaps the case that LG TVs do not literally do what you suggest here, i.e. upload literal screenshots of what might be private, confidential or proprietary information and sell those screenshots, and that you are being hyperbolic or repeating without verifying unsubstantiated claims made by someone else?
What is outrageous is that LG does this.

Also the LG pc monitors use the windows driver install process to auto install malware on your computer.
Avoid LG at all costs.
