I couldn’t find it again, sorry. But it wasn’t any real brand that did this (yet), but cheap noname TV clones (similar to those Trojan horse android boxes). Not something you’d trust anyway, but didn’t expect them trying to bridge the gap to get telemetry.
I have been searching for the source, but can’t find it anymore between all the WiFi troubleshooting sites. It wasn’t really brand stuff they mentioned but cheapo TV clones they checked for security risks, similar to those Trojan horse Android TV boxes.
But wouldn’t be the first time that the industry takes inspiration from something like that and either implements it silently to get the juicy telemetry (yes, using that to enable smart features would be dumb) or sells it as a ‘feature’.
The question is how long that will help. Just recently read about the first TVs popping up that try to connect to any available open WiFi to phone home, regardless of your settings. Soon our TVs will need tinfoil hats 😱
That might be a hot take.
