Right. The world is the USA and the rest of it is UK&Australia. If that wasn't the case, why would the aliens always contact the US president and speak English? iMessage is definitely the dominant messaging platform of the humanity.

The cluelessness of the Anglosphere about the rest of the World is very entertaining and sad at the same time.
I don't know why people don't look at India more. And China too, but in this case we know the Chinese use WeChat. India has about 3 times more people than the US, UK and Australia combined. China and India make up more than a third of all people on Earth, but rarely ever mentioned.
Indians use Whatsapp, and so does the fourth biggest country in the world, Indonesia.
It is always shocking when people make such baseless claims like "Everyone users iMessage" when a very simple google search would show them this is not the case.
It is a very big world out there and so few realize this.
