It probably has a lot less to do with loyalty to a country than it does with the quest for the "easy button".
The assumption that people are choosing a country strictly from loyalty is flawed in that it allows little or no consideration for the fact that some log on with the country with greater numbers in order to ensure they have the advantage.
The assumption that people log on for a real fight to see how well they fly is left over from a long gone era of flight sims when flight sims were very different from other games in their player base. The day when flight sims like Aces High and previously Air Warrior were populated by aircraft/warbird/history enthusiasts who were looking to fly and fight like the real fighter pilots of history did are gone. Sure, some of the diehards from the "old days" remain, and some of the new players fit the old mold, but a large number do not, probably a good sized majority. Expecting "gamers" to look for or work for an "even" game is probably asking too much. ENY limiting was something of a solution, although it brought about plenty of its own issues.
