It's not a true exclusive in the traditional sense but it is one. The closest term to describe it is console exclusive. It's less effective than true one, though. The point of an exclusive is incentivise people into buy one gaming platform over another. So it makes sense, that the more platforms that the game can be played, the less effective it is as an exclusive.
So people who say that "Why do I need an Xbox One when I can play it on the PC" are correct. Especially with most of the xbox one's new exclusives being console exclusives. People are having less reason to buy an xbox one and xbox one x. Just buy a pc with win 10 on it and you're good if you want to play those games. The PS4 doesn't have this problem since most of the it's exclusives are true exclusives. If you want to play those games, you can only play them on one platform.
Lastly, the point "If a title is released on both the Xbox One and the PC, then it's exclusive to Microsoft. So Microsoft reaps the benefit whether the title is bought on the One or a Window based PC." is really just silly.
Who gives a shit about that unless they are a MS employee or someone who has stock in the company. It doesn't matter in the way some people want it to in a debate about the xbox one not having much incentive for people to buy it.. "So microsoft reaps the benefit whether the title is bought on the one or a win 10 pc....." is really just a consolation prize type of comment.
