This key issue isn't whether or not things are changing (they are) or whether it's good or bad (that's debatable).
The key issue is who gets to decide.
If I want to tell the world a million things about myself, that's my business. But if someone else wants to tell the world things about me (especially if they know it's personal or private), then that's definitely not cool.
It's not that much different for institutions, companies, or any group in general. None of us should be surprised at the reaction of another whose digital cherry we popped on-line.
This reminds me of the old tale about the man with a gossiping problem who went to a sage for advice. The sage told him to slice open a feather-filled pillow, shake it outside his house, then come back tomorrow. The next day the man asked the sage what to do about his gossip problem. The sage said, "Go gather those feathers."
