I will be short here. Many people started complaining on the benefits of Microsoft forcing its DRM on us would have. While some policies like being able to access your games on any XboX One as long as you log your account were detailed, others like the Family Sharing, cloud computing stuff and the Steam like cheaper prices are far from being thing Microsoft promised or/and detailed.
Microsoft never detailed the Family Sharing plans beyond saying ten people would be your 'family', no need to them to be actual family or live in the same address. But they never said what strings they were attaching except that only one person would be able to play the shared game at any time. Rumor says that the person on the shared family would only be able to play one hour tops before the game stopping and a store prompt appears.
If you think Microsoft would kill used games and just allow ten people to pay 60 bucks and play a game in full, you are lying to yourself. Microsoft would never lose money selling less copies of a game when their old DRM was made to sell more copies. MS didn't detailed the plan before because they likely knew the details would make the feature less appealing.
Second, cloud computing. Microsoft is saying how much better games will be with it, failing to tell people all the bad things about it, like lag, the fact that it needs big servers to do it(way more than to just handle on-line matches). Also, the fact that all this benefits only work as long as their servers are online. What happens if they go down? Or that they decided that your old game doesn't deserve space on the servers?
Last, people say Microsoft would push gaming prices down going the route they were going. Why? What reasons we have to believe MS would low their prices, when they would have total control over the games? The only digital store in the Xbone is the MS one, and they could as well say the retailers that want to participate on their trading program would need to follow their rules on pricing. Steam prices only get cheaper on sales and promotions, and because there is several other online stores you can go to.
So, any attempt into making Microsoft dropped DRM seeing good is by wishful thinking. Nothing in their announced policies state any of the benefits many people want to believe they could get. I am glad MS dropped their policies, but in no way they would take a hit for the benefit of the customer.
