The gaming industry should just admit it, no matter what copy protection software they use, it will be cracked (from what I´ve observed, every new release has been cracked in max. 2 days. Even the ArmA´s own integrated FADE protection was cracked ,IIRC, just hours after the first patch release). The single player games have lost the battle against piracy loooooong time ago.
Like it has been said, they need to think of a way to attract people to buy the real thing. BUT, adding merchantise to come with the game, also raises up the prices.
