This whole case has been a dumb waste of time for anyone but scurrilous headline writers.
The plaintiff insisted on filling out the copyright app with their "creation" in the author field. Every legal opinion since has had to start assuming that's true, making "no copyright for you" legally obvious. The plaintiff apparently tried to walk that back on appeal, to argue he authored the work using the software. There's a paragraph right near the beginning where the court points out it simply doesn't consider that argument, since it wasn't brought up to the Copyright Office, back when the plaintiff was insisting on the opposite.
