Ah but which "mother version"? American English is closer to the original spelling than British English, but getting the actual English to change their use of their own language because the Americans use it differently seems... odd. Plus there's no intrinsic reason to prefer the original spelling over later versions.

So maybe we should all use English as it is used by the actual English? But that would see a small minority of the number of English-language speakers setting the rules for the huge majority.

So maybe (as others have suggested) we follow the majority of native English speakers and use the Indian version?
