Their motivations in doing this (rather than other things they could do with the resources) seem a bit abstract. From what I understand, it is not possible to move into the newly created universe. (You may be able to get some information into it, but it is limited.) So this would be a purely altruistic gesture, creating what they hope are new universes, ones which are forever independent of their own, and in which life might someday evolve.
The problem is that they have to destroy resources in their own universe to do this, shoving useful matter and energy down the throat of the black hole. Not to mention the cost of moving stars around or whatever is necessary to create them. It's not going to be easy, so this is far from a cost free endeavor.
No doubt some people would be interested in doing this, but it is
questionable whether it can rival natural processes in terms of creating
