I have helped a large government lab and their legal counsel to do a
license transition on Open Source with a big external developer community.
We know well how to do it.

XFree86 *forked *twice when license decisions prompted the developers to
decide that their current management was an impediment to the project. It
didn't destroy the project either time, it just made a particular
organization irrelevant to its future.
