From my understanding the oh-my-fish project has been around for a while and likely has some size of following. So the problem I see is the members of the organization using that existing notoriety to gain credit for the work the Wahoo creator did without citing it as his/hers. The fork and re-add wouldn't have the desired effect then because likely the core audience of OhMyFish still wouldn't see it.

Although I'm not sure if I'm missing something here as well, your guess is as good as mine.
