So this doesn't actually get into the actual big issue with MOND which is that observational results [1] tend to imply some sort of dark matter so current MOND theories actually include some dark matter, just less of it.
They include some non-luminous matter, but only require 1/5th to 1/10th as much as would be required by Dark Matter theories. So I think saying they require 'Dark Matter' is confusing. They don't really require a new class of matter and could easily be explained by the presence of some amount of non-luminous baryonic matter in some cases which hardly seems outrageous.
non-luminous baryonic matter has long been a contender for dark matter, I think the technical term is Massive compact halo object aka MACHO (as opposed to WIMPS or Weakly interacting massive particles) so saying it still requires dark matter is accurate we could rewrite it to 'actually include some possibly non-exotic dark matter'.
Because even though it reduces the amount of dark matter required it still has missing matter.
"While the Bullet Cluster phenomenon may provide direct evidence for dark matter on large cluster scales, it offers no specific insight into the original galaxy rotation problem. In fact, the observed ratio of dark matter to visible matter in a typical rich galaxy cluster is much lower than predicted.[14]"
