A bit of a leap to assume that your Apple ID (or the name you give your iphone) is your full legal name ... or related to any name at all ...
My apple ID is built specifically for just that phone and is jettisoned when I upgrade/change the phone. The apple ID is not related to my own name.
I don't consider this an aggressive - or even interesting - privacy practice.
Did you use your full legal name when you signed up with Blizzard for WoW ? Why would you do anything different for Apple ?
They are not the IRS. They are not a passport agency. They are not the government. Stop treating them that way.
