I’ve been harassing my dad for ages over his purchase of a WiFi-enabled LG fridge.
Neither of us know why it’s connected - but it is, and it proudly displays a WiFi icon with a backlit LED right above the water dispenser.
The only thing you can possibly gain from a WiFi-enabled fridge (it has no voice commands, no screen, etc) is just being monitored and/or hacked. There is literally no benefit to the consumer from having WiFi on that device.
