Talking to a coward I realize but the thing is Apple by virtue of the Apple id has much more specific user info than probably anyone but Facebook. They make you login to get free apps and such so it isn't just your purchases it is every interaction in their store, what you chose to download onto your device etc. all tied to a real person. Facebook is potentially worse because they know more about you than what flavor of condoms you prefer (your friends, your conversations, friends of friends etc).
If you are worried about Apple finding out where you live when you signing up for an Apple ID, keep in mind that when you sign up for G-mail Google is parsing your personal correspondence. Google is also archiving your search history, you can disable search history in your account but they probably keep tracking it nevertheless. If you start using Google Docs they may also be parsing that data. I'm not sure what their policy is on photographs that you upload to Google+/Picasa Web Albums but you are probably not going to like that either if you are worried about Apple knowing your name, mailing address, email address, and phone number. Also, why would you be more worried about Apple finding out your: name, mailing address, email address, and phone number than you are about Amazon, Barnes & Noble or Ebay finding out the same data?
