Nothing but upside
Not being bought into the Apple ecosystem, I can only see upside to this patent; since Apple don't license their patents I'll never encounter this intrusive stalking crap on any device I own.
If I weren't so happy about that, I might observe that this seems to be another example of a "something that's been done many times before, but on a ..." patent application. I can see that wifi mapping might be novel enough to patent (and doubtless is), but to then patent every GPS-based navigation or tracking application, "but using wifi mapping", really is nonsense.
