This is not really news...If the media had their way they'd force you to buy a new copy every time you turned around (Sorry, this copy only plays when you're facing east, you need to buy a new copy for when you're facing south, west and north). Of course, even without DRM, the internet is playing a big part in how much control the media has (and I'm not talking about Piracy, I'm talking about self-publishing).
Also, while steamworks is DRM, it's not as tightly clenched a fist as the other DRMs trying to force you to only be able to install it x number of times, or forcing you to buy a game twice if you happen to have a PC and Mac. Most of the reason why steam is loved is because they give you a lot more freedom to enjoy your games on YOUR terms. Really the only thing that would make it better is if they allowed you to share a game with a friend (and game sharing was found in the code so that may eventually happen).
