In a traditional model, if the consumer is not willing to pay for the product, then they don't get it.
With digital products, consumers have the (possibly illegal, unauthorized) option of getting a copy free of charge from someone other than the producer.
If consumer is willing to pay for the product, and if the producer is not authorizing copies of it, then the consumer (in theory) ought not get the product. But yet they are getting the product, because they are sidestepping the producers copyright.
isn't that capitalism 101?
