Seems likely to me that it was Beckstead, but that it was less rude than the podcast makes it sound. Beckstead is pretty straight talking, and might have told someone that the Future Fund wasn't interested in funding Global Poverty interventions rather than schedule another call. And after FTX's downfall it's natural for people to tell stories about interactions which cast the FTX side in a negative light (since it helps distance the speaker from FTX).
