While nobody can guarantee anything in life, we still expect reasonable policies and protections to be available. Otherwise why would anyone even worry or talk about the Cambridge Analytica scandal? Take this unrealistic example: would you not feel you're being scammed if you bought a flight ticket but the airline had no policy about baggage loss or delays (essentially anything that could affect you, the paying customer, negatively)? It's quite obvious that the airline cannot guarantee that your bags won't get lost or that there won't be delays in the flight times.
