After taking a brief moment to acknowledge this is all farcical anyway, ostensibly done in good humor, and is probably the least important issue of our day; I will state for the record that Australia and New Zealand have a combined population of 29.87 million people. That is less than the state of California.

If the other 430+ million native English speakers across the rest of the current and former commonwealth, and virtually all other compulsory english-as-a-second-language nations generally refer to and understand Kiwi to be a flavor more so then a flightless bird or a demonym, regardless of any dictionary, then that is now the principle meaning of that word in the English language by usage and valid by default.
