Papa Johns Can Predict When Your Fridge Is Empty

hmm. seems a little dystopian, but wrapped in a friendly 'oh they have no groceries lets advertise them a pizza'

anybody got any scenarios, following the same devious pattern, but with nefarious or more serious consequences. ? Some company sells my data, some other company uses that data with another company to send me a highly targetted advert.

in fact is this already happening, what is novel here ?
