Valve is a good company, so I doubt that they would pirate anything. I didn't say anything Valve being pirates. DRM is to prevent piracy/protect copyrights, and Valve's Steam platform is used as a large third-party DRM platform to activate games. My issue is that other large developers like Activision take advantage of Steam being at the top of the PC platform market, so when you purchase a Call of Duty game or pretty much the majority of any games from store shelves, they all require Steam Activation. There is no (good) reason that you should have to activate Call of Duty on Steam. If Activision wants to protect CoD from piracy, they should either make their own online platform or find a better way of assuring that the games aren't copied.
