You're scaremongering. Well, trying to- in practice you're just showing that you're a troll.
A mobile phone that didn't allow anyone to keep track of where it was would be of limited use... and as for Snow Leopard and Safari, it's up to you- if you're that paranoid then just turn Location Services off.
I think you'd have to do the same in Windows?
Yeah, that's it -scaremongering by commenting on what's actually happening. A bit different to other scaremongers who comment on what isn't actually happening. Of course the iPhone isn't spying on you, that's why it creates a log on your PC and makes sure it's backed up. After all, if you've done nothing wrong, you've got nothing to worry about.
However, it does look like it's recording your location history and the two researchers were quite right to raise their concerns. By making the app public, they made it easy for others to research and discuss the issue - on discussion forums.
How revolutionary.
How scary.
