Numbers, cuts etc etc.

A billion is a big emotional mark. Breaking it down to a per unit, regardless of what is actually given out as revenue, is a fairly traditional means of giving an indication of the per unit revenue (even if unfairly distorting).

Eg: cost of military + war in Iraq (in particular) is often distilled down to the cost born by each man, woman and child in the USA - despite the fact that each man, woman and child does not bear an even cost (nor some would argue an even benefit).

That is perfectly acceptable.

But the author is claiming that the developers are not making money with it and he's using flawed logic to get there. That's not ok.
