It's not a stupid idea, he no longer enjoys making this game anymore. Making a "small update" to finish off the story would a stupid idea because he no longer enjoys working on this game. Without the care and love for it, the product would be painful for him to make and ingenuine to the story he was trying to make. He isn't giving up entirely either, he just started on the wrong foot and is taking a couple steps back. There isn't any purpose for a comment to just insult someone and tell them they should make a quick completion to a complex story.
Please give devs a break, they need it badly. I hope you understand.
