And it's a good thing to admit that we don't know what's going on. I think the objection is that the terms "dark matter" and "dark energy" appear to be designed to give the impression that we know more than we do.
If we substitute P (pixie dust) for dark matter and M (magic) for dark energy we haven't actually got to change the equations.
This doesn't change the investigative science but it might redress the balance in the weight we give to scientific pronouncements based these things in the layman's mind.
"Dark matter is stuff we know is there but can't detect with today's instruments" and "sometimes the results don't tally with expectations" sounds like homeopathy with better jargon.
Undefined stuff with undefined effects is not strong science. That doesn't invalidate the idea, but for laymen, a caveat of "Here be dragons" might be more enlightening, even if it does strip the scientists of some of their priestly robes.
