That's simplistic here. I wouldn't be surprised to hear 'Ivory Coast' on BBC radio, because it is much easier to grok. But I don't imagine the BBC thinks that's the real name of the country. Diplomats are supposed to be able to hack French pronunciation. Let's face it, most anglophones can't. However WP is a written medium.
