The reason for this is that counterfeiting of most products seems only to hurt the firm whose products are being pirated. When a producer makes a purse and pretends that it is from some major fashion designer label, it is only the designer label that seems to get hurt. The person who buys the knock-off is satisfied because they have gotten a purse that looks like the real thing for a lower price. Many people do not really see big companies as potential victims of crime. The attitude is that these companies have so much money that they can afford to have their products counterfeited. In addition, they might figure that the person who bought the knock-off would never have paid full price for the real thing.
For these reasons, people think that either no one has been hurt or that the party that has been hurt is a big company that can afford it. Therefore, there has been no real victim of the counterfeiting.
