The website makes further arguments: English is the official language in many other countries, therefore choosing the UK is arbitrary.
You could define a complicated rule to make it less arbitrary, but then the choice of the rule itself would be arbitrary. I think the point that any mapping will be to some extent arbitrary is correct.
The problem for me is arguing that because any arbitrary convention will be offending or confusing to some, then no convention should be chosen. As opposed to the practical idea of just picking a convention that makes sense.
