Nice analogy.
People don't think about the value of the data most of the time Have a look what happens when they do:
"Survey respondents said the most valuable data was personal income, followed by the email addresses of close friends and family. Demographic data is less highly valued, although it’s incredibly valuable to fraudsters. The total value however is significant: £140 (€170) per consumer"

Tim doesn't want to look the gift horse in the mouth. But when we do just that, the proposition doesn't look like such a fabulous deal. And that's counting the opportunity cost of market destruction.
