Sorry, really quick reply from work--I hope we can talk more!
I would argue that pro writers are often influenced by and reacting to pre-existing works of pro fic -- that's different in magnitude/scope from fan fict writers re/vising (or not!) the canon, but it's on a spectrum--and of course some professionally published fics are transformative (parody) (THE WIND DONE GONE! THE WIDE SARGASSO SEA), but even beyond those obvious examples, "reacting against genre conventions while still being influenced by it" is a real thing (despite the idea, esp. in the anti-fanfic circles that "original" fic is totally pristine, new, original never thought of before--which is SO not true).
I teach creative writing (and allow fanfic) but even those students who have never heard of fan fic start by writing incredibly derivative works based on what they're read....they're not pro authors, but I bet every pro author starts out more or less the same way!
