It's like saying that if you give free newspapers near the metro it is possible that more people will read them.

The only problem is that here they are giving for free "paid newspapers". So, everyone that wanted a paid newspaper but didn't have the money to pay for it read it more times because they were able to steal them.

By this analogy the conclusion adds that the fact that people are able to steal newspapers helps to keep everyone more informed.

Now, please do the same analogy for food.
