I completely agree with all your points, but to be fair iOS dominates desktop Mac in terms of revenue to begin with ($51B iPhone + $7B iPad vs. $7B Mac). That&#x27;s reflected in the fact that Apple continues to open source XNU on desktop (granted, not in anywhere near approaching an open-process, or complete, manner) but not on mobile. Apple has historically been more willing to open source things they don&#x27;t make money on (e.g. LLVM and Swift). Seven billion dollars is a far cry from zero revenue, but it&#x27;s an interesting trend nonetheless.
