This is probably the most important question to be able to answer effectively, though I (and it appears many others) have trouble coming up with a compelling reason why people should be worried. Most of the people I try to convince remain unworried, thinking along the same lines -- why is it bad if they know more about me? I inevitably try to explain that 1) it's not beneficial to you, and 2) more importantly, bad actors could use the information unscrupulously. However, they believe that if this information is helpful in any way in protecting them, and otherwise doesn't really bother them, then it's a positive trend. I would like to come up with some powerful (frightening) examples of why the data collection going on is so dangerous, and why people should be worried and careful.
