The MAGA side of me says BOOM for this post! I Follow Back!
Yea, my TV and receiver both have Wi-Fi/Ethernet and I keep all that turned off and disconnected. There have been reports of Samsung sending voice command clips back to their network, and I even found telemetry on the TV enabled by default.
I route everything into a Pi4 running Kodi. The LibreELEC version supports HDR10 content now and full AC3/DTS/TrueHD passthrough.
Note to self - Never hook up stolen electronics to the internet
