> To make it harder for stalkers to abuse them, Apple included (and has since upgraded) several safety features that will alert someone to the presence of a nearby AirTag that’s not their own, including an audible beep.

Is this saying that Apple is relying on the unknown tag to announce itself by emitting a beep, and is that true?

I think you want your management device (e.g. phone) to alert you to the presence of such a thing, not that thing itself.

(Of course, you still need to find it.)
