My question is how would a user know their TV is being used like this?
Also this is the reason you down download random crap onto your devices.
I have an LG that is connected on its own network with bare minimal apps (netflix, prime, etc) because it's too convenient for my family. I actually bought it because it didn't display ads on the home screen like the other smart TVs I'd researched. Thought LG was the lesser evil, turns out they're all a bad as each other.
Only reason LG doesn't have adverts is by forcing it to use a pihole, but even that needs updating -- recently they've managed to push things through and I need to do another investigation to see what needs blocking. Trouble is I only see them when I'm not in the mood to be working, and then forget about them
