Ranking common countries first only seems like an issue because of our sensitive political climate. Or do you still think it's "perverse and elitist" to put commonly bought bus tickets before more rarely bought options like season tickets in ticket machine menus?
I don't think that's a good analogy. But my comment reads way harsher than I intended it. I've probably done it myself in the past – sticking a handful of key countries at the top of the selector. My point is it isn't good design, it's a lazy hack. And I think if I was a user from one of the 2nd tier countries, I'd find it pretty elitist. The ticket machine analogy doesn't apply.
