Simply put, What the hell are you talking about?
The game until July's "Gold Edition", had a single optional DLC, and even after the "Gold Edition, it's still an optional DLC.
Why? This is why.
Pre-order GreedFall to receive the Adventurer’s Gear DLC Pack containing the following in-game items:
Explorer’s Outfit: perfect for any adventurer embarking to strange lands, the Explorer’s Outfit is said to bring its wearer good luck and fortune. This complete outfit contains the Hat of the Discoverer, Doublet of Good Fortune, Gloves of the Craftmaster and Weighted-heel Boots.
Rapier of the Alchemist: crafted by a master alchemist of Al Saad, the blade of this rapier ignites when drawn, with the ability to inflict terrible wounds.
Wild Boar Ivory Rifle: this elegant rifle isn’t just for style. Though less effective at longer distances, a short-range blast is more than enough to stop a charging boar in its tracks.
The Adventurer’s Gear DLC is going to be made available for purchase after the release of the game, so don’t fret if you miss the pre-order window.
It was a Pre-order Bonus, and then sold for a small additional cost, and like every preorder bonus ever, is optional content that gives nothing more than a small start up boost.
Like most pre-order bonuses, if they are ever sold at all, they rarely get added to a "complete edition", because that reduces the perceived value of being a pre-order bonus.
Excepting this rather insignificant content, which is still kept as a separate purchase for the same exact reason, the game has ALWAYS been sold "Complete".
It was "Complete", when you made this ridiculous claim in April.
It's still "Complete" now with with the not that surprising release of the original PC version, aimed at "Next Gen" consoles, "Gold Edition" now, but at least there's a small DLC included for PC owners.
