Well, only Americans use it. There's no point in arguing about it your version of a language is better or worse but for the rest of the world it's incredibly annoying having to correct Zs with Ss when using LLMs or American only software.
That's certainly not the case in the majority of Europe, Australia, New Zealand, East Africa, West Africa, South Africa, PNG, Fiji, Philippines, South Asia and South East Asia. Really it's mostly just America and Canada that use American.
American forms are definitely dominant in the Philippines, even in an official capacity. I can't comment on Africa, but I would also characterize SEA as American-leaning in the wild; en-gb dominates in education but largely illusory. Elsethread the same claim is made of the "majority of Europe".
I honestly don't think this is true. In many places outside the US our devices will default to US spelling, making it appear as if the language spoken by the locals is US English.
But when you look at things like the type of English being taught in school, or the language used by the government, it'll be UK/International English.
Kinda forgot India is still part of the Commonwealth. Maybe because all Indians I ever corresponded with uniformly used US spelling, likely because they work a lot with the USA. YMMV.
