A rough estimate of the number of HTC Android devices shipped is 30 million. If HTC paid $5 per unit to Microsoft, that adds up to $150 million Android revenues for Microsoft. Microsoft has admitted selling 2 million Windows Phone licenses (though not devices.) Estimating that the license fee is $15/WP phone, that makes Windows Phone revenues to date $30 million.

It is easy to understand that no one wants a Windows phone but why is Microsoft being paid for Android? Because Microsoft is allowed to threaten competitors with patent lawsuits.
