Author Stephen Hill, a "journalist in residence," makes a rhetorical point by implying that today's $5 Uber fare really ought to be $10 if Uber weren't subsidizing passengers, and that today's customers are "only paying half the cost of the ride."
Uber's willingness to incur losses in the name of growth is still quite astonishing, and a measured analysis of its growth strategy would be worth reading. But the gap between 10% and a rhetorical 2x is huge. Many other journalists are taking time to do the math. I'm not sure why this math-impaired version found itself a big headline.
