We already knew that Microsoft makes more from Android than it does from Windows Phone 7:
Microsoft gets $5 for every HTC phone running Android, according to Citi analyst Walter Pritchard, who released a big report on Microsoft this morning.
It also turns out that Google makes more off iOS than it does on Android:
As part of the Senate Judiciary hearings today, former FTC official (and new Google employee) Susan Creighton, testified under oath today that Google, Microsoft and Yahoo! all bid to become the default search engine on iOS’s Mobile Safari Web Browser. […]
[A]s part of the testimony, Creighton said briefly (before she was cut off) that 2/3rds of mobile search comes from Apple iOS devices.
Such is the bizarro world of product development funded by legacy monopoly money (Windows) and advertising (Google).
