Andy Dehnart of Reality Blurred's piece in Vulture.com lays out the timeline and what we know to date, with useful links.
• The interview where Kellee was asked by a producer to speak up IF there was an issue comes in three weeks after she talks to Dan (first episode). The "If" is unconscionable, the "three weeks after the fact" for me only reinforces why Kellee answered the way she did to a question that she should never have been asked in the first place.
• Castaways not directly involved (e.g., inappropriately touched by Dan) were unaware of the true extent of the situation. The scene we were shown of castaways laughing about it only helped reinforce the idea that it wasn't serious at all to the people Dan didn't touch.
• The talk producers had with each castaway did not link the reason for the talk to Dan in any way, nor did it even make clear that complaints had already been made about inappropriate touching.
• Probst had tried to quit Survivor after Gabon. He became more of a showrunner and --more tellingly-- a "storyteller" afterwards. The inference is that continuing conditions for high drama/conflict is more important to Peachy than risking a safe and possibly "boring" season.
I was especially intrigued by this last point, so I went to the link provided for the New York Times article: https://www.nytimes.com/2015/10/01/business/media/survivor-defies-gravity-to-hang-on-as-cbs-ratings-stalwart.html
"Years later, though, the show was drifting, Mr. Probst said; he said the low point was Gabon, which was broadcast in 2008. He said he felt burned out and was also a little self-conscious about being known as the “Survivor” guy.
“My Achilles’ heel for a lot of my life was that nobody saw me as a storyteller, that they saw me as a white guy with dark hair who was just a game show host,” Mr. Probst said. “And that in terms of my own self-image was the thing that could gut me. It was like a kidney punch.”
The frustration and exhaustion were enough that in 2009, Mr. Probst went to Mr. Moonves and quit, he said.
Mr. Moonves told him to take a break, and Mr. Probst took a few months off, returning to the show re-energized. Some changes were made to the production team, he said, and then he focused squarely on the show’s success formula: serving the loyal audience and not worrying about doing more than that."
Both pieces add that Survivor was and has consistently been one of CBS's reliable workhorses, costing much less than other shows, and with one of (if not the most) sizeable audiences.
Given that, it sort of explains (for me, anyway) why they went ahead and put this season on air and edited it the way they did, with Peachy clinging to this season as proof of Survivor's cultural relevance in the #metoo and #woke era. It also explains why they seemed completely surprised at the backlash but still remained silent, forcing us to endure THs with Dan and treating him as if he were likely to end up as a Final 3 up until the last few minutes of the penultimate episode.
