Tracking a kid at an amusement park, presumably a quite young one, is entirely fine IMO. I remember when I was 4 or so, I waited until my parents weren't looking to sneak off and go play with a toy in the gift shop my parents didn't let me see earlier in the day. I just about gave them a heart attack.
Ah yes. This statement is more terrifying than Apples half-assed PR fireball a few days ago.
The same folks who bought iphones because its has better "privacy" than Android...
...are using iphones to track their kids whereabouts. It's like a dystopian punchline masked in the Friends laugh track.
