This is relevant to me. I just hooked up a TCL (Chinese state owned TV company) to the internet yesterday for firmware updates. Even though I reset the internet connection afterwards, I have no idea what type of nefarious thing it can do, or if it truly forgot my WiFi password.

To rest easier, I actually banned it’s MAC from accessing my network. Even that is probably not sufficient.

All of my viewing is through my Apple TV, which in my opinion is the most privacy-centered company in silicone valley.
