It isn't. Both are equally valid because both are a result of an individual's own thoughts on the matter. But a few people continue being vocal about how they want interactions that support a non-monogamous interpretation removed wholesale, while the people who interpret it that way are kinda just here to be like no reading it the other way is fine and valid please don't simply remove it entirely, it'd be cooler to improve on it.
Oh, my bad then. I must have misread it as implying that was a canon set in stone. My apologies.
