Maybe I'm just an "academic in charge" but I don't understand how MOND being able to account for galaxy rotation curves means that dark matter is not real. There is missing matter in galaxy clusters. Matter is missing if we look at galaxy-galacy and cluster-galaxy strong and weak gravitational lensing. This matter appears to be non-interacting (see Bullet Cluster, El Gordo, etc). There is missing matter from the angular power spectrum of the cosmic microwave background if we only account for baryons. There is missing matter if we are to forward model gravitational collapse of large scale structure at early times. MOND doesn't explain any of these things.
