You can buy Android apps from the Android Market in only 13 out of 46 countries and you can only develop paid apps in 9 countries.
Of course there are third party Android app stores but who knows about them? Do they advertise? Are they being promoted to potential Android buyers? How do operators fit in to this equation?
Google is an advertising company. Android’s existence is a vehicle to deliver ads in the mobile space. Having
a large library of universally accessible paid apps is counter to Google’s reason to have Android.
