Steve Jobs describing Apple’s stance on privacy at the recent D8 Conference:
Privacy means people know what they’re signing up for, in plain English, and repeatedly. That’s what it means.
I’m an optimist. I believe people are smart, and some people want to share more data than other people do. Ask them. Ask them every time. Make them tell you to stop asking them if they get tired of you asking them. Let them know precisely what you’re going to do with their data. That’s what we think.
The privacy discussion begins at about 1:09:30 into the full video of the interview.
