It seems to be related to some advertising push from a partner named Alfonso that is gathering information cross-platform anything that appears on your screen and pushing advertising to you during playback.
Hopefully not, but that’s what it looks like from early reading.
My LG, and all other TV’s in my home are disconnected from the internet, because of ACR and ads. I use a seperate setup box. I did have a pihole blocking most of the smart tv telemetry, but I still did not trust the smart part of my tv.
