Open source developers with attitude problems? Surely this has never occurred before.
To be less sarcastic: Does it matter who the developers are and how they behave? If the source is open then it can be reviewed by anyone. If it works, there is no reason not to use it.
If the project is toxic (no pun intended) that's good enough reason to have nothing to do with it, period. If the above is true, a fork with a less-hostile community/development-environment would be a Good Thing.
