Just because you tell your friend a secret doesn’t mean you’re happy when he tells others. Same with your employer, your bank or any company you do business with.
But as the Facebook example illustrates, privacy is much more complex. It’s about who you choose to disclose information to, how, and for what purpose. And the key word there is “choose.” People are willing to share all sorts of information, as long as they are in control.
A great analysis of recent events. Thanks for the suggestion, Karissa.
