1. He went to the summit, which wasn't recorded mostly to allow people to be open and share their private stories without fear

2. Something about that summit didn't sit right with him, so he wrote up this document and send it as feedback directly to the organizers (not openly)

3. When he got no response back (it's arguable if organizers should reply to every single feedback, but you can also argue that this was a pretty big one), he posted it to an open but not huge discussion board (skeptics) specifically made for people to argue ideas and have discussions.

4. Eventually, it caught some attention outside of the board and it blew up across the entire company

You were pretty close but just wanted to clarify a couple small points.

Rather, I present my honest assessment of the strengths of the various pieces of evidence, pro and con. If I "want to be proven wrong", I certainly wouldn't present a falsely certain argument. That is not arguing in good faith.

And that's how I would argue a scientific question, not an argument about my coworkers ability.
