Guest network of your neighbor. Or your neighbors neighbor until it finds an unprotected network. That's part of how mesh networks work. Below is a reddit post with someone claiming this happened to them on a Samsung TV and it's not the type of thing that's out of the realm of possibility because so many devices will default to automatically connect to open Wi-Fi signals in range.

LG in particular are known to have axed the ability for apps on the TVs to set up or run residential proxy nodes on their customers wifi, but notably don't mention disallowing it for their own apps or system os.

So it may be a rumor, but it's not beyond the realm of possibility.

If you're connecting a computer to an LG TV it's better to remove its ability to gather and send data. Physically remove the wifi chip and disconnect Bluetooth module/mics as necessary.

These things take screenshots including when you open up utilities like your wifi settings and do things like input passwords. Best practice says it's probably not enough to just not connect it to the Wi-Fi and hope for the best.

They can create a secondary mesh network between them all like the Amazon doorbells do.

Now it's been explained.
