This is a very fuzzy memory, but I remember a report of a smart device that "helpfully" automatically connects to other devices nearby, forming a mesh network.

In other words, even if you never connect your TV to your WIFI, it might be enough that your neighbour does.

If anyone has any more info on this I'd be very interested in seeing it

The parent post is probably referring to Amazon Sidewalk, a mesh network formed from Echo devices and other Amazon smart ~~garbage~~ devices, launched in 2021: https://arstechnica.com/gadgets/2021/05/amazon-devices-will-...

I don't think that's the same. Amz Sidewalk is very slow, low bandwidth over sub-GHz. What GP is thinking about is probably along the lines of, if not getting Internet access by the owner, willy-nilly connecting to any open wifi network it finds, and uses that.

But "meshing" with other apparatus from the same manufacturers is a clever and evil idea - perhaps another TV from the same brand is in range and has Internet, then they can proxy that way.

All these probably break some regulations or laws.

I tried searching for it, without much luck. I don't think I was thinking of Sidewalk, though. It was more like some TV manufacturer like TCL, LG, etc. The best I could find are some unconfirmed reports of devices automatically connecting to open WiFi, which doesn't quite match.

But I can't find anything now, so it might be best to consider it apocryphal.

Did you know that HDMI cables have Ethernet running over them?
