This is a style rule that we have here: Don't "correct" international English spellings (like "humour" and "favourite"). The spellings are interchangeable, and one is no less correct than the other.

As such, changing it constitutes what we call and "empty edit" where the article was not improved by the change - (and frankly suggests an inflated sense of superiority in our American users...)

Anyway, empty edits are frowned upon here, and that is a kind of empty edit. (Of course, changing it back would be an empty edit too, so, I'm not gonna do anything about it).
