Even if the EU could force it, you will have to wait at least.. 5 or 10 years for anything to change. With the EU decision pro resale things are in motion but they move slowly (And you can believe that Steam is not "unaware" of the legal situation....) if Steam is smart, they do it in some way that makes it a publisher choice and thus delays the entire thing by another 10 years. But it will come, the EU courts ruled consumers have a right of resale, and consumers can SUE for this right. Although it would be a long and expensive (if uninsured) battle since you would have to go up to the highest EU court. Since this involves international trade the EU has a nifty arsenal to force companies to comply, the EU is the second largest gaming market in the world. And no publisher could afford punishment or even exclusion.
