According to research by Rice University and Duke University not using DRM on software will actually cause a decrease of piracy. Analytical modeling was used to see the impact of enforcing DRM or not on digital media. The increase in piracy while DRM is enforced is caused by the negative impact on legit users who have no intention to actually do something illegal. They have to pay the price, like not being able to legitimately making copies of music cd's or not being able to play games offline, while pirates will crack the software anyways being able to do the aforementioned things. Thus, legit users will opt for the illegal route, because they can do more with their product.
The research also revealed that copyright owners don't always benefit from less piracy.
Decreased piracy doesn't guarantee increased profits. In fact, our analysis demonstrates that under some conditions, one can observe lower levels of piracy and lower profits
