EDIT: Just to be clear, the parent's post was originally made in relation to an article/thread called: "LG smart TVs caught logging audio with screen off and snooping on local devices". My response was written at the same time.

> So the video doesn't seem to support the claim in the article that "LG smart TVs continuously [...] log microphone audio while appearing to be turned off".

While it is a bit unclear as to whether the logging and transmitting of audio is happening[1], without hacking the device, they were also quite clear that they made it extremely difficult (if not impossible) to MITM certain encrypted communications on their consumer devices. Combining that with claims they make about advertising makes LG's actions highly suspect.

While the video is quite clear that they are not saying LG is doing this (for legal reasons), the set out to prove the capabilities are there and the privacy related configuration options are very weak. For example: the microphone switch only controls one of the onboard microphones. Even if it physically cut off all of the microphones, there are other vectors that could only be software controlled (such as voice enabled remote controls).

Either way, whether it is LG or a third party, the capability to log and transmit audio can certainly be exploited.

Perhaps it is time we start considering whether we should do something just because it can be done. That is to say: do we really need to control a television by voice, or have other features that require a microphone, just because adding a microphone is cheap and there is enough compute to process the data?

[1] I got the impression they were claiming that the audio was recorded and stored on device. They simply could not prove it was sent to LG.

As far as I can tell, all the recording, storing and transmitting of audio from the microphone happens after 34 minutes in, after the point where they start hacking the TV and telling it themselves to do these things.

LG's advertising features appear (from what they discover before 34 minutes in and from the clips of the LG execs boasting about their ad platform) to be concerned only with what's played on the TV (and networks, devices, ..., but not microphone audio).

If I'm wrong about this, I would appreciate a timestamp for where in the video they show LG actually storing and transmitting audio recorded from the microphone.
