I explained it to a friend one day as: 'a cardboard box at the end of your driveway.' "I keep all my nude selfies in 'a cardboard box at the end of my driveway.'" "I have my entire company in, and all my money comes from, 'a cardboard box at the end of my driveway.'"... People need to understand how thin their security is when they rely on the cloud. You have no control of your data/service.
