I think the reason is different. Some languages have official bodies that decree how a language works. For example the French have the French Academy.
English has no "boss" in charge of how the language works and who decides what the correct anything for the language is. The closest are style guides, but they come from multiple organisations and each often different to each other. So, it's harder to just decide that something will be spelt differently.
