Not weighing in on the broader issue here or, necessarily, why the author included that bit (see what I'm doing?) but pedantically qualifying one's position and every single clause to the point of absurdity is a style people learn when writing for online audiences, because something about reading text online makes people even worse readers than they ordinarily are, which is saying something, while also making them feel like well-informed experts on every conceivable topic who definitely need to comment on the thing they just read and (generously) half-understood, while also for some reason assuming the writer is some kind of actual fairy tale monster until proven otherwise.

Above sweeping statements intentionally left without pedantic qualification because it accurately expresses my thoughts on the matter as written. Deal with it, Internet.
