You mean, so they would lose their royalties and give Valve free money? They would be better if they simply sent trucks loaded with cash for Gabe Newell's house for free.
I mean, what would they gain with that? They would just share money with Valve for nothing (because they already have digital sales) and lose control over the games on their own platform. It doesn't make sense in the slight form.
And if you mean because of Steam prices, that's just because they use always online DRM, so the games can be sold cheaper because they aren't really a full license of the games. If MS had gone with their plan on X1, that's what we would have down the road: cheaper games that nobody really owns.
