I didn’t say it was geography. American culture is mostly separate from Australian culture. As the US is a unified cultural element, it’s not surprising that a single standard had been established. The downsides of the lack of this are easy to observe: just look at the EU. No single unified language, no unified market, less economic power. Making a Netflix for America requires 1 language, while making a Netflix for the EU requires 29. China isn’t pushing Mandarin everywhere just for chauvinist “cultural superiority” reasons.

It ultimately comes down to politics and economics.
