I was studying the following paper arXiv:2502.18352v1 [gr-qc] 25 Feb 2025 "Primordial black holes as cosmic expansion accwelerators" of authors Konstantinos Dialektopoulos, Theodoros Papanikolaou and Vasilios Zarikas. In the appendix they are talking about the role of SdS spacetimes as expansion accelerators as they could explain early inflation if Λ dominates with respect to the mass density of the black holes. My concern is that in most cases the black holes in SdS spacetimes should evaporate due to Hawking radiation and lead to an even smaller mass, leading to a smaller mass density ρ and with this constituting a positive feedback loop where the inflationary behaviour enhances in time indefinitely instead of ceasing like we see in our universe. Although it is true that for a particular choice of initial conditions such black holes should anti-evaporate (as shown by Raphael Bousso and Stephen W. Hawking in "(Anti-)Evaporation of Schwarzschild-de Sitter Black Holes" (1997)). Is this what was intended in the paper or could this be a "correction" for the SdS case?
