More a controversy than a disaster. The last commits [0] are only about governance model, discord link... There are some rebase but that's it. Nothing will probably come from this fork.
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.
