It is of course stupid that iOS doesn't sandbox and require permission of apps to access the address book. Apple needs to fix this. But it is not enough. I keep a lot of data about people in my address book in addition to phone numbers and email addresses: birthdate, names of children and spouses, residential and work postal and physical addresses, gift ideas, group affiliations, etc. I am happy to click "OK" if an app asks for essentially the social graph information that I've already exposed through Twitter and Facebook. I don't want an app to have the other data I've curated. Even if you can trust the app vendor to not be evil, you can't guarantee they won't leak the data through incompetence. So while Apple really should require permission for apps to get access to the address book, we really need a new model more sophisticated than all or nothing.
