That's an interesting point. They forced the end of every manufacturer using unique charging cabled for their phones, forcing a universal app API would be a great step. The phone would literally just become a platform and you could have a healthy competition about who builds the best platform.
the API would not have to be universal, because that would mean android support on IOS. the API would just have to be open, in that neither apple nor google can act as gatekeepers for who gets to use it.
this also includes that apple can not disallow duplication of existing features.
