> Sooo technically this is on the edge of legal/not legal, depending on your intent and what the judge had for lunch that day. ID'ing devices without consent is a grey area at best.

It's looking at the BLE advertising packets that they send out to everybody. The only thing stored is manufacturer ID, not a device ID (which you wouldn't be able to get anyways).

You might as well try to press charges against Apple or Google for putting readable names for nearby devices that aren't yours in the bluetooth pairing screen.
