Cybersecurity bounty hunter says Samsung TVs use AI to record audio and screenshots for ads
(www.tomshardware.com)
All of the ACR “features” and the audio capture features are behind separate, optional EULAs that the TV will work fine without. The GN video about LG was behavior if you agree to every EULA as well. You can add on a pi-hole and a smart tv blocklist for added protection, e.g., https://github.com/hkamran80/blocklists/blob/main/smart-tv.txt
It’s very easy to setup Wireshark and capture the traffic coming off your devices as well if you want to be sure.
