The ground is already lost. Apple can't prove that their monopoly is worthwhile, and none of their detractors are willing to renege. The "issues they see in different ways" ultimately boils down to one objectionable product (the App Store) that Apple is unwilling to part with.

Apple can fix this issue without excess complexity. They are the ones demanding fragmentation and disparity as a result, allowing alternative app storefronts has always been a one-size-fits-all solution.
