I remember there was a lot of misunderstanding about Google's revenues from Android when everyone started writing articles about it a few months ago. Most of their "facts" came from 2010, when Google still had like 4% of the US market, and Apple had like 20-23%. And somehow they extrapolated that to mean that Google also makes 4x less from Android
right now. But Google has grown much faster than Apple since then, and by now Google has caught up even with the total amount of iOS devices (iPhone, iPod touch, iPad), and they both have around 350 million devices on the market. So it's very unlikely that Google is still making much less from Android than they do from iOS.
There's another similar kind of misunderstanding whenever Apple releases the "money they have paid to developers". First they forget that Apple only ever mentions the total amount they have paid since the App Store was created in 2008.
They also forget that again, Apple had a huge headstart in both number of apps and in number of units in the market until late 2010 or so, and that only more recently they've had about the same amount of apps and number of units in the market as Apple.
So when you compare the "total amount" Apple has paid to devs to Google's "total amount" that they paid to devs, obviously Apple will come out on top because of their huge headstart in the first 2-3 years. But if you compare the last quarter or last year for both, which is a lot more relevant for devs, because they'd want to know how much they can make right now, Apple might still come out on top, but the difference should be a lot smaller, and definitely not something like $3 billion vs $100 million.
Hopefully the "Apple media" will remember this before they start slamming Google when Apple will release their new numbers, without really understanding the context of those numbers.
