Sounds like one of those "what if..." things someone made up. AirTags are terrible for surreptitious tracking, alerting every iOS user nearby of a tracked product following them around. I mean, years ago people, such as stalkers, would use it for this purpose, but Apple rightly gimped that. There are a lot of specialized, self-connected trackers that creeps and criminals use.
Well, to be historically accurate: Apple has pretty much been forced by the backlash to notify people that they're being tracked and even then it only worked if you had an iPhone. They knew what they were doing and I'm sure the stalking aspect helped their sales significantly as it seems to be a very popular behaviour in the US.
Virtually any tracking or surveillance has a knock-on effect that we often overlook in our enthusiasm, but Apple absolutely should have foreseen the abuse that would happen, and certainly profited off of it.
