MOND remains popular because it's made so many successful a priori predictions that DM failed to do. At the risk of being too reductive: DM is popular among maths-oriented astrophysicists because as physicists they like particles and deep theories, and MOND by contrast, doesn't have a full theory justifying the adjustments to gravity and they don't like that; MOND tends to be more popular among astronomers than astrophysicists because they like effective theories that make successful predictions using few parameters, and MOND is somehow better at that (as with this paper).
