Google has every right to be able to develop their OS and license it at whatever terms or cost they see fit especially when they ultimately benefit consumers. MS tried to use their cash warchest (acquired from their Monopoly markets) to acquire offensive obvious, broad landmine patents that they hide behind NDA's so to not disclose exactly what patents Android is supposed to have infringed on so that they can extort licensing fees from Android Manufacturers into artificially raising the prices of Android devices.
