I don't think it's that fandom is prone to confusing fic with reality/tinhattting, it's that this particular fic (I gather from this thread) plays into a tinhat theory that already exists widely among a certain group of fans. I can't judge the author's mindset, but it wouldn't surprise me if anon who said the author kinda meant it to be a little bit of a "thesis statement" was right, either.
