Interesting. That could explain the disparity of experiences being discussed here. I have all my emails in LinkedIn to be discoverable by colleagues, so that means LinkedIn also knows they are specifically me and I'm signed up.
So both your experience and the grandparent's are possible - they respect you, once you've signed up.
