DRM for those wondering, is a security measure in place to make sure you're the person who owns a game or software. DRM to my knowledge requires an always online connection as well, to make sure it's you who is playing it. It would periodically check if you have the disc in your drive. Thankfully I don't think it's a big thing anymore. But I think there are companies that still put it on their games. With that being said, do you hate DRM? I can't stand it because there are still games that still require you to be online to play and it's odd when it's a single player game.
