That's to separate things that clearly are driven by different reasons: * Do ads make products they appear cheaper? If so do they make other things more expensive. * Are products not paid for by ads cheaper due to automation, etc.? If so could they be even cheaper if not for ads? I would say munging them together is intellectual dishonesty.
