Well, the Mormons booted Quinn out.
The Saints don't like to talk about Hugh Nibley very much either, especially after he authenticated Joseph's translation of the Egyptian Papyrus (re. Book of Abraham), and then spent the rest of his long life backing down (i.e. "I never really actually did say that") after being dismantled by some real Egyptologists.
He also denied he developed "Nibley's Challenge" concerning Joseph's authorship of the BoM after the Tanners demolished his arguments -- even though evidence of Nibley's involvement is, in my opinion, conclusive.
