Granted, I only watched one hour of the original video, but I get the feeling the way it is presented is a bit dishonest.

A lot of the "silent listening" they show in the video is on a TV they rooted. They start recordings through arecord manually. Or, when they show the transcripts from the recording, the AI voice search is clearly visible on the screen and was manually triggered by something.

Now, does a smart TV need all that hardware? Is a compromised TV a security hazard and smart TVs need to learn more in terms of security from modern smartphones in terms of privacy indicators, attested boot and more?

Sure.

But I do not see enough evidence that the TV is actually voice capturing all this stuff on its own, without any notice.

There is plenty of stuff on the video regarding the network scanning, ACR and more that is definitely concerning. And this is something LG actually does by themselves (when you agree to their ToS / privacy policy).

However, I think that mixing the ACR / network scanning in with "let's root the TV and actively start recording ourselves" mixes the narrative of "what LG actually does" versus "what a compromised TV can actually do", and makes it seem like LG is just recording, transcribing and submitting voice transcript automatically by themselves.

This was not proven here. And I feel that GamersNexus is just risking a lawsuit here by not separating these different concerns clear enough.
