There's no control just like there's nothing stopping people from recording your conversation in real life and passing it around the office. Sure, on the Internet things are easier, but it's the same concept that you can make it socially difficult to reshare certain things.

Saying "If you don't want it to get out, then don't put it on the Internet" is coloring things too black and white. What about those tech articles that you'd like to share, but don't want to annoy your non-technical friends with? What about the nonsensical updates that you're _okay_ with people seeing but _would rather avoid_ having certain people see?

Not everything that people post are naked pictures or incriminating evidence. There's just some things that are socially awkward to share, and that's where "control" comes in.
