Maybe in the future someone catches Section 31 so they can't attempt genocide anymore...
They are finally brought to justice by the 25th century.
The existence and activities of Section 31 were exposed to the general public by the early 25th century

I hope we actually get to see this in a future novel.

If you look at it from the POV of an attacked race, it's humanity's fault for the survivors not letting themselves die. They went back and sought out the Caeliar's help to survive, had they just allowed themselves to die or killed themselves, no Borg.
There are a lot of races that will have this viewpoint, I feel. The Klingons, for example. A Klingon would never be so weak as to allow themselves to even *be* taken prisoner, let alone used in that way.
AAAA! Hell no! The whole fucking POINT of this massive series was to totally, irrevocably and permanently END the Borg. If the MU Borg pop up, that will be a galaxy-sized middle finger to the fans.
I don't know what will ultimately happen to the MU Borg. I doubt that we will ever find out. Perhaps "The Worst Of Both Worlds" will prove to be definitive? We can only hope.
