Yes, Blondie that is accurate. When several (including Ray and wife) of us met at Peter Gregersons in the early '80's there were a couple of people there, one in particular, who were very blunt in their negative feelings towards Ray. She expressed openly that she felt he "left" because he was forced out and only then did he feel compelled to write CofC. She felt he shared the guilt of the GB in many of the things he exposed.
Ray was a very humble man. He accepted the criticism quietly and without any attempt to make a vocal defense. I respected him for that. After all, he titled his book "Crises of Conscience" didn't he?
