Seems like you created quite a narrative there, given how 3 of those points are nowhere to be seen in this thread, and the fourth one, what little there is, doesn't name MS anywhere.
Yet you're encouraged to believe this same thread with Naughty Dog and EA Motive (for example, take another 200+ third party studio that you want) would only reach 3 pages of "oh this is super fine, Sony is the best :)", which is just absurd.
This thread reached 15 pages because it's a really weird and unusual collaboration between two enormous studios. This doesn't happen normally. It's not hard to understand.
I have seen someone ask why The Initiative would need help.
I have seen people propose that the game might have been in some development hell.
I have seen someone state that Microsoft having bought a good amount of studios, then partnering with a third party studio to get things done is not a good look.
I have seen people ask why not get some of their studios to partner on this. One that has been mentioned severally is Arkane.
I have seen someone concerned that Crystal Dynamics will take time before they are in position to make another multiplatform game, otherwise read as a game on PlayStation.
There has been concern that Crystal Dynamics is joining mid development, and not at the outset.
IIRC, there has been someone who has asked why The Initiative does not just grow themselves.
I could go on. This is not a model that is different to how Forza Horizon has been a collaboration between Turn 10 and Playground.
It is not different to Mistwalker working with Artoon on Blue Dragon and Feelplus on Lost Odyssey, no different to how 343i partnered with Creative Assembly on Halo Wars 2, or The Coalition with Splash Damage on Gears Tactics. World's Edge is essentially a partnership between World's Edge and Relic.
The only thing that shocks people is that Microsoft has come to an agreement with Square Enix to work on this title.
Heck, I am even reading people trying to justify Kojima and Guerrilla working together as being different when it is all outsourced work. Movements by Microsoft seem to attract some weird reasoning that is rarely evident elsewhere.
