Actually I remember this story when it happened. It was played all over the media and the personality of Jim JOnes was analyzed ad nauseum. I believe the dead bodies at Jonestown made the cover of either Time/Newsweek or People magazine. It was actually hard to believe it was true at the time.
NOw, as far as the money connections being exposed, I cannot remember if that indeed was brought to light at the time.
The MSM of the day treated the Jonestown saga as yet another example of the evil of organized religion. Still do. They concealed Jones' militant atheism, his mocking of "the Sky God," etc. In short, business as usual. IIRC, Rosalyn Carter was another very public fan of JJ's.
