no but they do have an Apple ID which is link to my phone number and I have a feeling Apple will use that to link everything up.
If Apple started using your billing phone number without your consent to force you into iMessaging, don't you think they'd be sued left and right, and have government hearings on privacy violations? Good god. How far from reality are you really trying to take your paranoia about a feature you don't even have to turn on?!?!?
Maybe they'll take your credit card number from your apple ID and start you a Gevalia coffee subscription too? I hear that free k-cup machine they're giving away is rather nice. The odds of that happening are about the same.
