When you share your content with family and friends using Apple products, send gift certificates and products, or invite others to join you on Apple forums, Apple may collect the information you provide about those people such as name, mailing address, email address, and phone number.
So when you send a product they may collect the address to send it to? Or if you invite someone to join a forum it may collect the email address with which to contact them? Absurd.
When you create an Apple ID, register your products, apply for commercial credit, purchase a product, download a software update, register for a class at an Apple Retail Store, or participate in an online survey, we may collect a variety of information, including your name, mailing address, phone number, email address, contact preferences, and credit card information.
So when you purchase something using a credit card, or add a credit card to an account, they might collect other information which credit card companies require in order to prove your identity (and make charge-backs less likely)? Inconceivable.
Clearly this information collection is not for the same reasons or in the same league as Google or Facebook's data trawling.
