The crazy part of this is that LG did not fear flat out admitting they do fingerprint the audio of what you watch. I already knew that, but I can't imagine it's common knowledge yet. How long ago was it that that would have been the crazy untrue accusation?

ACR is a documented feature so they can't deny that it exists. https://lgads.tv/technology/ https://www.consumerreports.org/electronics/privacy/how-to-t... (note that this is from a year ago)

Not defending LG's stance, but hasn't LG always said they do this as part of ACR (automatic content recognition) for the purposes of targeted advertising?

LG says it's opt in, and I think the devil is really in the details about what the consent screen says, but the only way I think it would be a "crazy accusation" is if LG was doing this without consent.
