ELI5: Facebook privacy and does that disclaimer I'm seeing actually do anything?

I've been seeing a lot of people put up a disclaimer (skeptical that it even does anything) but why exactly are people flipping out? What's the worst possible outcome and are my kittens in danger?

The disclaimer is a good way of discovering who in your friends list has a high school level understanding of contracts and End-User License Agreements, Terms of Service, etc. 

Legally it holds as much ground as going outside and saying, "I declare bankruptcy" does to ease your debts.
