Earlier quoted context omitted.
Sam Altman. There was an attempted fix and that fix failed. Evil prevailed because of public misunderstanding and mob mentality. Be real, who else would permit this? Paul Graham fired him from ycombinator. I'm pretty sure if the public didn't support Sam he wouldn't have been reinstated.
I think they failed due to not having the courage to admit why they removed Altman. Their messaging was extremely weak and uncertain, a complete failure to communicate anything of value, until everyone was rallying against them.
There is no clear marker that a evil person is evil until the crime is committed, but you can know someone is not a good person simply by knowing them and talking to that person. It's clear they knew what kind of person Sam Altman was but they had no clear marker because there is no crime, yet.
Sam was fired from ycombinator by Paul Graham. That should be enough evidence something is not right with his character, but his firing was kept private and not publicly advertised out of respect.
