And yet in his own words, the "most important reason" was to prevent other companies from using cross-platform libraries (such as Adobe Air) on the platform.
That reason was reversed, and Adobe Air (including what was essentially compiled Flash) became available on iOS.
It was never reversed, and you're missing the point. Flash as a runtime environment -- with its own stack, VM, APIs, and process ID -- was never allowed on iOS, and only barely was available on other mobile devices. What you linked to was Air, which allowed you to write applications in ActionScript and then generate Objective-C.
This is worlds away from a reversal. You were still using Cocoa to interact with the device, not Flash.
