It's also worth noting that Sama actually did provide for their employee's mental health. They didn't do a good job of it but trying and failing at a thing doesn't quite qualify at the level of disgust imo. Especially not for the company that was outsourcing this.
It's also worth noting that even if those of us in the peanut gallery would not trust the word of either OpenAI or Sama, it is not unreasonable for OpenAI's team to have trusted that Sama was doing what they said they were with regard to providing for their own employees mental health.
From the article:
"That month, Sama began pilot work for a separate project for OpenAI: collecting sexual and violent images—some of them illegal under U.S. law—to deliver to OpenAI."
