They made up their contorted Social Expectation. Most of us have never really thought of what we expect our friends to be able to do with our information. I think we all assume that we trust our friends to occasionally share too much but you have to trust them to some point to just use their best judgement, even now they can go share your email anyway.
One way network grabs are cheap tactics. A user should be able to leave a network with the data that's been entrusted in them, just like with Address books, Calendars, or other trustingly shared data.
This is all about crippling the convenience of people leaving their network for competitors. You can already share with out permission, just not easily. This isn't about protecting our privacy, it's just about slowing down our power to go elsewhere at will.
