I think most of those comments are missing the real point here. If an Apple product were ever used to stalk - or God forbid, harm - an individual, it would be a big national story. If a Tile or a Samsung tag (or an amazon gps tracker made for stalking) were used in the same way, it would likely only be mentioned in passing if the story were reported at all.
That's why it's so important for Apple to do this. Additional benefit - this may push other vendors to do similar things, pushing stalkers back to more tailored devices. That's still helpful, as it's a lot easier to show intent if someone uses a device like that (as opposed to 'whoops, I lost my airtag).
