This sounds like a wonderful Cydia / iOS Jailbreak app opportunity. MobileSubstrate allows easily hooking system methods. An app which replaces the Address Book API with something returning empty data for all non-system apps seems pretty easy and quite urgent. Morin and company need to provide an "opt-out and wipe all of my contact data now" option if they don't want legal action and backlash, as well. Simply making the app require opt-in to share this data in the future isn't nearly enough (and, especially in the EU, isn't legal). Update: I'm working on a MobileSubstrate tweak to neuter AB* functions in non-Apple apps, and it's now possible to get your information wiped from Path... by emailing service@path.com.
