Well, let's look at the assumptions they begin with.

 1. INTRODUCTION Ordinary matter constitutes about 4% of the closure density of the Universe,
That is only true according to Lambda-CDM theory. If you don't subscribe to Lambda-CDM theory, (for instance you're a MOND theorist) this statement is false.
Incorrect.

The conclusion that ordinary matter constitutes about 4% of the closure density of the Universe is derived from the standard BBN processes taking place in a universe that expands according to GR when it is dominated by radiation.

In that case $p = \frac{1}{3} \rho c^2$ and the scale factor is given by R(t) $\propto t^\frac{1}{2}$.

This sets the limit on the time for nucleosynthesis to continue.

Dark Matter and Dark Energy have nothing to do with it.
