Wow, thanks for pointing this out. I'll do a mea culpa then. I was uncomfortable making Google the final arbiter of place names, as I didn't find a good reason why we should trust Google more than the democratically elected government of our country.
But I really like this policy. Even though it still relies on Google's definition of "common usage", it makes naming much less arbitrary and more sensical.
I was wrong in my previous analysis. Google had a clear, sensible, defined, published policy, and they broke it to appease a wannabe autocrat.
