I actually just don't get why, architecturally, a platform should have any incentive (besides business) to favour this app or that app.

You can see how this becomes complicated when Twitter & FB both recieved integration, as they both directly compete with each other in a number of spaces.

This kind of deep integration should've been done at an API level, where the user has more control over what kind of apps are deeply integrated, rather than the closed system that Apple supports.
