That is, don't publish your personal information if it is related to others, unless they gave you permission to do so.
More generally, never impose your own decisions on others.
Let's say you don't trust Google. But your friend does, and he stores your name, address, dob, work email, private email, and mobile number in his address book. What now?
Now let's say he has uploaded some photos of a bbq you were at. You notice somehow because you don't want the photos of you up there. He responds by making them private. Now you don't know. What now?
