I am by no means qualified to judge physics papers of any kind so take this with a grain of salt, but the invocation of Maxwell's Demon (a thought-experiment method of violating the 2nd law of thermodynamics) suggests it's presenting a pretty fringe idea I think. However, this supposedly happened prior to recombination and, if you can imagine it, I'm even less qualified to guess at the veracity of claims about that epoch.
