Already been done. They said it was due to customer feedback, which was probably part of the reason. When the majority of customers say a company policy sucks and as a result they're buying competitor's products instead, it's a good idea to change the policy. Although they never said it, I suspect they realised that it was decreasing sales and increasing piracy because of something really rather obvious - Ubisoft's DRM policy annoyed most potential customers and made pirated copies greatly superior to legit copies.
But whatever the reason, as of late last year Ubisoft's publically stated policy is that they no longer use always-on DRM.

The Ubisoft people bend over backwards to avoid saying it was a mistake or that previous comments from Ubisoft were mistakes (they describe them as "unfortunate comments"), but they are clear about it being ditched.
They also, perhaps unintentionally, clarify that the widely publicised very high figures about piracy are wrong in that they only apply to some parts of the world and for some games. Or so they claim - like every publisher they refuse to provide any evidence for any claims about piracy. For all we know they're just making numbers up.
