It was in the national news back then for a while, but I guess they didn't obsess over it. We didn't really have the 24/7 news cycle back then - they just gave us the news and moved on.
One of my roommates in college was linked to this story. He had a twin brother and when his parents got divorced, he and his twin brother were separated (they were very young at the time). His Mom and brother got involved with this cult, and he and his Dad stayed in Texas. At the time I knew him, he never really even knew his twin brother - I just could never understand that. He was pretty embarrassed that his Mom was caught up in all of that, and he told me he really didn't even consider her his mother. Pretty sad.
I was like 9 at the time, and didn't really pay attention to the news. But I grew up hearing about Jonestown and (later) Waco, and still hear about them to this day. Of course, those cases ended with a bunch of corpses and Rajneesh didn't (although apparently not for lack of trying).
The series basically ends with Rajneesh's arrest. I think they could've added another hour to tell some of the stories of the broken families like your roommate's, and if they ever reconciled.
Still an engrossing binge though. Check it out if you haven't already.
