I think the story is missing a major point: What is the fee of those ATMs?
I disagree that this is a major point. The central innovation is turning on thousands of Bitcoin terminals overnight. The fee is a distraction. Those that find value worth the fee will use it, those that do not will not. If not enough use it, the firm will lower the fee in order to induce others to use it, maximizing sales and thereby profits. The market will end up setting the price.
