That's completely ridiculous. Even if the exact figures in the articles are wrong, it's still generally accepted that Google makes a significant amount of its mobile revenue off of iOS. Demanding that I unearth some vague "report" to give you specific figures is completely meaningless. Doubly-so since it doesn't even matter what the numbers are, because the whole point was that Android users switching to iOS are still extremely likely to be using Google products, which means Google's still making money off of them.
