I haven’t found anything calling this crank science, although it does make some rather sweeping claims. One is that dark matter does not exist, and another is that the universe is 27 billion years old.

Dark matter theories have had competitors for a long time. MOND is a pretty significant one.
A helpful thing to keep in mind is astrophysicists are well aware that theories of the “age of the universe” are closer to that interesting thought experiment phase than a more concrete sort of harder theory. This stuff is still many years from being nailed down even a little bit.
