I was in the same boat as you. It doesn’t sit right with me having all the smart stuff enabled even if I’m not using it. There’s plenty of concerns there. I ended up getting a smart tv, using an Apple TV plugged into it, and turning off the WiFi on the tv itself. When I want to update it, I can. Otherwise, you can look for TVs marketed towards businesses. Like the ones that get hung up to display menus and stuff. That was the only avenue I found where the smart stuff wasn’t baked in. They’re expensive though.
The real time chat abuse reporting is pretty interesting. Hopefully it’s tuned well and you can’t get griefed by it.
