Think like a user...
The "access to resources" is pretty obscure, and people will always assume that this is what it needs.
If you want proof, just look at Facebook viruses. They only work because most users don't understand the importance of "send messages on your behalf".
Moreover, even though the program asks for permission, this is not enough to fulfill legal criteria for "informed consent". The permission was gained while withholding the recipient's intent.
And if that wasn't enough, reread the article -- the app doesn't close when you exit. Without warning, it continues running in the background. Even if a user is happy with the GPS information being collected for whatever reason, he still has a reasonable expectation to opt out by closing the app.
