I don't even see the point of having SecuROM in the Steam version at all. What are they trying to accomplish? Steam requires a login so you can't share the game with ten of your friends. The Steam version doesn't have a CD so no CD-check can be performed. Unlimited installations are allowed so no need to keep track of that.

It's kinda ironic when companies are deliberately pissing off their customers for no reason whatsoever and then complain about people who pirate the game to get rid of all the DRM crap.
