The issue is not whether it acts like regular matter.
At issue is, rather, whether observations consistent with DM as formulated should be privileged over others that are not. Current behavior of cosmologists is that inconvenient observations should not count, and need not be paid any attention.
That is why the authors bring up sociological explanations for cosmologists' behavior. It is not scrupulous science.
