It is always either that the license is not permissive enough, too many changes are required that upstream wouldn’t merge and its would be hard to keep rebased, showing the world that they can be absolutely independent, or not having enough experience and experts for given stack. Maybe I missed some reasons, but that’d be all I think of.

Either way, if it’s open sourced our company might switch.

It is actually not hard to extend the software. I, for example, set up automatic uploading of cal recordings to a Peertube instance.
