So what? I have the option to NOT register or sign in to a Google account AND to turn off Google Maps location sharing. DONE.
Do I have the option to NOT use Apple Maps within iOS 6? Sadly not. Being the default mapping app, any address link in Safari or another app like Yelp is going to send me me to Apple Maps. And does Apple data mine me when using their Maps app? Of course they do!
So what's your point again?
Also, if you REALLY want to know how Google uses the info it collects on you, go to: http://www.google.com/ads/preferences
They even allow you to CHANGE your own profile or REMOVE anything you don't want there. Quite sinister, isn't it?
Seriously, you really don't get it. This is similar to when companies offer a rebate for an item you purchase. They do this because most people will forget or not take the effort to fill out the form and send in the copy of the receipt.
Of course they allow you to make those changes and remove anything you don't want. That is to abide by privacy laws. But most of the people that sign up with Google either do not realize this could be an issue or they don't even know you can make those changes.
