By now, everyone and their pet Rancor knows that George Lucas officially stated that he intentionally based Star Wars on Joseph Campbell's concept of "The Hero's Journey" from his seminal "The Hero with a Thousand Faces".
Obviously, plenty of SFF works consciously or unconsciously followed this model (there's a reason Campbell described the archetype), and just as obviously, plenty do NOT follow it.
What I'd like to know is, who was the first SFF author who explicitly stated that their work did NOT follow Campbell's Hero's Journey model for a specific reason (not simply "because that's not how I write" or "because this story is not THAT kind of story", but an actual specific reason to reject the model in a work where it could plausibly have been used).
I'm only interested in work created after Campbell published his book (or for a bonus round, after Lucas publicly referenced the book vis á vis Star Wars), and those where the creator specifically explicitly talked about his decision to avoid using the Hero's Journey model - using the HwaTF or Campbell by name - and stated the reason to do so.
