What the hell is that all about?
If this has changed, scratch all of the above.
Because there are way too many spouses who go to as absurd lengths as setting private investigators on their partners. Stalking is just as much a concern inside families as it is for everyday persons - I might be tempted to say that the impact is worse given the potential for domestic violence. Or just imagine fundamentalist parents tracking their children to Planned Parenthood, a known LGBT-friendly place or whatever.
Ideally, there would be laws and regulations on trackers - and not just hardware-ones like the AirTags, but also software-based ones - that mandate features to prevent abuse, but sadly politicians haven't caught up on tech developments yet.
Coercion, simple as that.
If A had to coerce B to turn of the alert, then the alert would have already served its purpose to tell B that they're being tracked by A. Moreover, there should still be some interface which B can use to figure out which AirTag is following them, so person B would 1) know that A is tracking them in general, and 2) have the ability to check whether A is tracking them in the moment.
Please explain what additional information or utility the continued notification is giving person B in this moment, or if my understanding of the hypothetical is wrong.
I want to track the dog, the shared cars’ keys. I want to track a shared bike. There are a load of items I’d put them on, but they aren’t just mine.
I don’t believe it’s a security thing. It’s the Apple way to get software to a point then just stop development, there are plenty of examples.
