The bulk of the whining I see here about DM is on the lines of "but it's not directly observable, so it can't be real science! Can't you see this is just Big Physics trying to fool you?" These are the ones trying to falsify DM entirely, and having to ignore huge swathes of evidence to do so. Yes, the paper suggests sterile neutrinos at cluster scale, with MOND at galaxy scale. I'm fine with this, honestly.
