Why doesn't Draco In Leather Pants use sourced examples?

Draco in Leather Pants uses general examples, while Ron the Death Eater only features specific fan-works. Shouldn't Draco in Leather Pants be the same?

If I had to guess why it's done this way, it's because Draco in Leather Pants refers to a more general trend in the fandom of taking villainous characters and trying to portray them in a more positive light. Ron the Death Eater on the other hand is often invoked by fanfic writers in order to make way for a preferred ship. As such, Ron the Death Eater doesn't necessarily represent a trend in the same way Draco in Leather Pants does.
