There are multiple versions of Wine out there, and the exact results potentially depend on the user's Linux distro, the exact versions of packages installed, the compiler version it's built with, ... One of the problems Wine developers have is that DRM is often very fragile and sensitive to software changes that are outside their control.
Also, other WINE users are posting saying they've had no issues.
The story's being spread around now, so I guess we'll see one way or another because other users with the issue will either show up, or they won't.
