The authoritarian shall always be more powerful than the libertarian, simply because he will leave with his wallet, if he find something that offends him, but the libertarian will not leave if he cannot find something that would offend the authoritarian.
Therefore, it is commercially more viable to keep the authoritarian happy.
That level of granularity isn't provided by Google in their financial reports, so Google as a whole.
That said, Android seems to be doing better outside the US than in the US.
I wouldn't be very surprised if US revenue was dominant within the Android BU (or whatever they call it today).
Last time I heard (probably outdated) there were at least 2 billion non-US Google Play devices active; compared to the 120 million US Google Play devices figure that's widely available.
Also: Wouldn't surprise me if Google makes more from licensing the Google Play store to non-US markets than they do from the Google Play sales revenue globally.
