I think they have succeeded in doing that. If they stay on, it will be under A&E's rules of censorship and I don't believe the Robertson's will compromise their faith just to stay on the air. At least I hope they don't.
Like you said, they don't need the money since they were already successful...
As it has been all along. They have said many times before the producers edit out "in Jesus name" during their prayers.
They have taken the view in the past, they will use the platform to get out the message that they can. And I believe because of the compromises they have accepted so far, they have gotten more of their Godly views out to many that would never have been reached.
But I don't pretend to guess how they will go forward from here.
