How is forking the codebase "the worst possible thing"? The open source landscape is filled with forks of projects that diverged for a variety of reasons. A fork means the people involved are still contributing code and it can potentially be merged upstream. The alternative is they don't fork, and contribute nothing because they're unhappy with the original project.
