How is this lowering the barrier? I bought a orbit for my keys that does exactly what this does, for cheaper, like 3 years ago. I would actually say nothing apple does about using this for stalking is useful in the least, because if someone wants to stalk you they can get one of a dozen devices, for cheaper, that would be better because they're not a obvious white and silver apple branded monogrammed thing. Noones at risk, because everyone already was, apple users included. As for the future of it, I think there's already a bike company building the find my system into their bikes, so probably anything high theft could make its way onto a network like this.
