I really liked this article
"You Can’t Opt Out Of Sharing Your Data, Even If You Didn’t Opt In"
"Call it 'privacy of the commons.' It’s what happens when one person’s voluntary disclosure of personal information exposes the personal information of others who had no say in the matter. Your choices didn’t cause the breach. Your choices can’t prevent it, either. Welcome to a world where you can’t opt out of sharing, even if you didn’t opt in."
