I thought one of the big use cases for this was to track stolen items, like a backpack or maybe even a bicycle. But the "anti-stalking" feature will notify someone if an AirTag they don't own appears to be traveling with them. Does this render it useless for anti-theft, then? Since it will just notify a thief that the bike they just stole is being tracked, and they can look for the AirTag and throw it in the nearest…
The anti-stalking feature also seems to contradict its privacy features:
> Bluetooth signal identifiers transmitted by AirTag rotate frequently to prevent unwanted location tracking.
But also, in the next sentence:
> iOS devices can also detect an AirTag that isn’t with its owner, and notify the user if an unknown AirTag is seen to be traveling with them from place to place over time.
If an AirTag is supposed to be "anonymous", then how can a user be informed that this tag has been seen with them over an extended period? This would mean that there is a way to identify a particular AirTag in the first place.
