As a customer, if I buy something which turns out to be stolen, I will not stop using it. The vendor who has been robbed is not being robbed by me. I see no reason why I should pay for something and not be able to use it. The ripped-off vendor must take a bit of a loss. If I have to assume this loss, then I will stop buying anything except from the most established vendors. These are not solid, concrete items like a dvd player. This is a copy, a copyright issue. I doubt any of the vendors could afford the legalities to stop it. The loss is a part of the cost of doing business. It is less of a loss than if I and all other customers begin to avoid new vendors. If I see a vendor harassing the customers who bought the "pirated" item, I will avoid buying anything from that vendor.
