If you're speaking a different language, using a different word is fine. But if you presume to claim to be speaking "English", then you should use the word they use in England.
This phenomenon isn’t unique to English, by the way. Every language spoken in more than one country (AFAIK) has some words that vary between countries.
Your argument is a bit ridiculous IMO, it’s like saying neovim should merge every patch that gets merged to vim.
