Probably worried about things like spectrum wifi. I don't know if others do it, but spectrum will sell access to a private WiFi network using their customers Internet as a backend.

LG could be using that sort of network.

Well even if they don't do it now, these are just a forced update away from using WiFi to connect to an open AP to do whatever they want. I also really hated the fact that there was really no way to turn BT off. Anytime the TV was on it showed up as a BT device ready to connect, and I would get random neighbors trying to and having to say no to random pop ups approving connections. Now these things are sans any type of wireless, and when it comes time to sell them, it will take me 5 mins to reconnect the internal ribbon cable.
