Well, that'd be kind of shitty because you've taken someone's work and altered it so it misrepresents the original work, all for the purpose of making them look bad. Did Moran do that with the slashfic? Did she edit it to misrepresent what the author had written, or to put words in the author's mouth? Or did they just read what the author had voluntarily written and posted to the internet?

I'm not sure your analogy is a good one.
