It's pretty clear that what we have here is a divide between those on the eastern side of the Atlantic Ocean and those on the western side (with a notable exception of a person from Israel with an understandable leaning towards usage in North America) and that due to systemic bias inherent in the system that the western side is going to win out, despite nearly 500 years of history. What really gets me though is the mantra from some people who say "I've never heard it as anything but Rio de La Plata", as if that ignorance was something to be proud of. I'm out of here.
