I think you're quite right in a sense, but let's say it had been Samsung making these promises. Do you think the system not working properly or producing weird and unacceptable results would have prevented them releasing it anyway?
Well, the results[1] are[2] actually[3] in. Samsung of course did do that and the results are what you'd expect.
So in a sense Apple 'could' have released what they had, after all Samsung and others have, but almost certainly not at the level of quality Apple expects. In which case arguably not releasing until it is capable of reaching that quality bar is the right call. The wrong call was announcing it in the first place when it wasn't ready.
