The problem is that Microsoft is only willing to pay for games that can sell millions and millions, massive earning games, they don't want to pay for games that sell well and bring good single player experiences. But making a multi-million game must be multiplayer and this is a lot more expensive and risky, but in case of success the earnings are great.

And, in my opinion comparing Ori with Fallout 4 and Horizon Zero Dawn is completely wrong, because Ori is an indie game, and the others are AAA, more complex, expensive, ambitious and big. I think this comparison reflects why Microsoft can't understand why the consumers criticize them for the lack of exclusives, they thinks and Indie game and a AAA game are the same. And don't missunderstand me, I'm not saying Ori is a bad game, buy is not a AAA like the other games.
