> One of the big open questions is "are APIs copyrightable?" The court skirted that question, and instead focused on whether it was fair use

Also what people fails to realize with fair use is that it is up to the defendant raise a fair use defense and then a judge has to approve of that defense as a valid one (Viva Frei explains this https://youtu.be/AzQz1LrjCWk?t=253 ).Meaning Oracle can still go on with its lawfare campaign against those who made the mistake of basing their tech on theirs.
