Ordinarily I think of a black hole as being a pretty ordinary gravity source when you are far away from it. If our sun got turned into a black hole by some non-violent process the planets would keep orbiting around it the same way around. How it contributes to dark energy is beyond me (like... nothing is supposed to leave a black hole!)
It reminds me of a 1970s sci-fit book where the bad guys were trying to prevent the universe from collapsing (people thought the universe was closed, not flat then) and managed to momentarily reduce the mass of the universe by manipulating a black hole so their evil computer could live forever in an eternally expanding universe. The good guys countered this plan with a ship that traveled close to the speed of light, increasing its mass, and causing the universe to collapse. On top of that they used a black hole to create a time loop causing the events that made the ship leave.
Needless to say, none of the above is expected to work.

I have to admit I don't get it.
