What FTX decisively disproved was the idea that people's origin stories involving apparently sincere desire to do good in the world and them constantly broadcasting that should be used as a reason to unquestioningly trust them when their notion of greater good happens to align perfectly with them accumulating enormous quantities of wealth and power. (and Sam, bless him, originally wanted to help animals rather than own the machine god. And probably sincerely believed he was going to do great things for humanity from all the misappropriated funds he was definitely going to win back against a backdrop of EAs and VCs queueing up to glaze him and his commitment to the greater good)

I don't think people are objecting to the EA idea that some charities are more evidence based than others so much as the distinctly EA idea that it would be more effective still to donate to charities like OpenAI
