Facebook, Twitter, Instagram and all the others once seemed to have our interests at heart; now that's looking a little more questionable; in the future, who knows where it will end? The problem is that subtle privacy changes creep up on us in such a way that we're practically oblivious to them.
If you drop a frog in a pot of boiling water, it will of course frantically try to clamber out. But if you place it gently in a pot of tepid water and turn the heat on low, it will float there quite placidly. As the water gradually heats up, the frog will sink into a tranquil stupor, exactly like one of us in a hot bath, and before long, with a smile on its face, it will unresistingly allow itself to be boiled to death.
