But OUT and OOT are not synonymous. OOT is the Original Original Trilogy, the sort of platonic ideal of the Star Wars Trilogy. It's been used for a long time to describe the original Star Wars Trilogy. OUT is Original Unaltered Trilogy, a new marketing term used to describe the 2006 DVD release of the Star Wars Trilogy. Since it's not the original unaltered trilogy, using that acronym represents a sort of intellectual buy-in to a lie. Prefixing it with the G acknowledges this and places the blame for the dissonance where it rightly lies.
