I'd like to see their working for that number. Let's say we subtract 20% from Canada + the UK + the US, we get ~320 million. add Nigeria and Uganda and you have easily 400 million. That's without Australia, Ireland, New Zealand or any of the African or Caribbean countries.

~60 million people in Nigeria speak English out of 230 million people, but that 60 million isn’t almost exclusively native speakers.
