I choose to quote a para supporting the default narrative unlike John Gruber:
That isn’t to say that Apple should be controlling and arrogant, and that their choices don’t create genuine problems worth bitching about. Nobody should pretend it’s good for consumers that Apple doesn’t let Nuance make Swype for iOS and doesn’t let us set Chrome to be our default iPhone browser and that it’s to my benefit that iCloud makes it impossible to use Byword on the Mac and iA Writer on the iPad to edit the same plain text documents. Apple definitely contributes to their own reputation.
