Well, it’s still a hack, not something officially supported, I wouldn’t really consider them DRM-free when you still need Steam to run the game officially.

I’m not ruling out Steam either, they’ve done a lot of good for gaming and I buy games there if I really want them and there’s close to no chance they’re coming to GOG (like the recent Dragon Age), but more and more often I decide that I don’t actually want that game that much.
