I saw something that said Josh was tied somehow to a business that was being investigated by the Feds. It didn't specify what/who, etc. If any other Duggars are connected, it might affect the show.
I do remember that after the Josh molestation scandal when they canceled 19 Kids and came out with "Jill and Jessa: Counting On", the show was centered on Jill and Jessa and their new marriages. and how they were coping/moving on. JBoob and Mechelle were not to be a part of it because of how they did or did not handle the situation with Josh. IIRC, JBoob was none too happy about losing that control. Josh and Anna were not to be a part of it because of the obvious. After the first season when the dropped the "Jill and Jessa" part, it seems as others have gotten married and everyone is starting to pop out babies like Pez dispensers, it's morphed back into something with everyone back in on it except for Josh.
What could they come up with next? "I Demand a ReCounting?"
