I think you guys are missing the point a little on this one. It's not that there is a picture of this dudes bare ass somewhere online and he's upset about it, it's that no matter what he did or tried he could be guaranteed in absolutely no way that the data was removed or under his control. Once it's in the pipes, it may or may not be there, there's no way to know. Anything you put online, in all sorts of incidental ways be it from giving your TV voice commands, sending your location to google maps, or your net connected security devices, becomes someones property other than just yours. Not that it's legal, or that people are spying on everything you do, but that you have no way of knowing about or controlling the data once it's there.

This isn't supposed to be scary, just a reminder that you can lose control easily.

This is a complex issue and if you think it goes away by saying things like "well then don't stand in front of the camera naked." then you are missing the point.
