Risk-taking and ambition are two sides of the same coin. If you swarm to denouncing risks that failed, you do not understand what it takes to succeed. My very subjective sense of people in the EA community is that we are much more likely to fail due to insufficient ambition than too much risk-taking, especially without the support and skillset of the FTX team.
Risk taking and ambition are two sides of the same coin when the parties who stand to bear the downside are the ones who benefit from the upside, and can consent. Appropriating user funds to bear the downside risk without their knowledge is not ambition, it is theft and not morally acceptable. If for example, Alameda had collapsed due to trading losses, but customer deposits on FTX were untouched, then it would be an entirely different matter.
