Maybe it's just a problem of being loose with terminology, but this seems to be contrasting entropy and information content, which is backwards?
Both have low information. The complexity rises and falls, peaking somewhere in the middle, as energy from the gravitational field is turned into structure.

Penrose likes zero initial Weyl curvature because it provides low entropy, but also conformal flatness, thus enabling his CCC theories.
Another consequence is that the Big Bang is not a reversed black hole (white hole). Black holes have high Weyl curvature. The Big Bang is the lowest entropy configuration, but a Black Hole is the maximum entropy configuration (just mass, spin and charges).
