Yesterday we reported Ubisoft was returning to its ill-received 'always on' DRM scheme for Driver: San Francisco. On its reasons for the change, Ubisoft says it's seen "a clear reduction in piracy of [its] titles which required a persistent online connection, and from that point of view the requirement is a success."
It's understandable publishers want to reduce piracy, but if revenues are no higher as a result of DRM and the DRM itself is a significant expense, it's difficult to see the justification. We asked if sales were higher as a result, to which the company declined comment.
In any case, Ubisoft doesn't appear to be as staunch about it as before: From Dust won't be using the system -- what protection as of yet is currently unknown.
