For example, my brother is not techy at all, but he's big into cars.
I asked him if he would enjoy Ford sending everything he's doing in his car to the mothership, then selling that info to insurance companies, or used for "marketing." (immediately he understood the issues)
Then I ask if he's comfortable with knowing that if he accidentally speeds, turns too fast, or breaks too often, he may have to pay more for insurance.
This obviously won't work for everyone. I do have the "i have nothing to hide" friends, but i ask them what if someone DID have something to hide? Not everyone loves "showering with the windows open."
