I don't understand why you thought i was talking about bringing them benefits, but since you brought it up, I often donate to projects I use and do extensive testing on git branches on nearly all the software I can.
but regardless, I wasn't implying that it would benefit them at all.
None of it is "that bad". However its understandable if contributors want to separate out and have a more open governance.
As long as they keep the licenses open where both projects can pick and choose. Some forks do so "maliciously" and change licenses to prevent upstream from pulling changes back.
