you have a narrow mind. Apple is in a business to make billions. they are not a small Joe business trying to make a few bucks. They are not playing any game you are imagining.
look at fact: apple is preparing to launch in China soon (with 8 million already pre-ordered). They are also launching in additional 40 countries. Does this have any affects on U.S stock? absolutely.
you might ask, "why doesn't Apple focus on U.S since it is their prime market?" well, they can but they risk losing retail partners/customers in other countries in long term. if you are in an international business, would you want to upset your partners/customers?
you might ask, "why doesn't apple anticipate this? why not build more plants and hire more workers?"
well, if they do this, 3 months down the road when this demand fades, these extra plants and workers sit idle, costing money. they don't add more capacity just for a few months of peak demand. just like Amazon won't add more servers just to handle peak load during a few Christmas days.
In fact, no companies can handle this kind of demand within a month like this, over 20 millions phones over many countries within a month. Apple logistic infrastructure is unparalleled.
I give them until november to be able to have walk-in stock. If not then its a conspiracy.
