Be careful here. Read the article closely, here is what it says:
> [Sama] said in a statement that its agreement to collect images for OpenAI did not include any reference to illegal content, and it was only after the work had begun that OpenAI sent “additional instructions” referring to “some illegal categories.”
Note how carefully this is worded - if Time could confidently say that OpenAI asked for C4 images, they would have absolutely put that in the article. Now, this is filtered through PR statements, but it reads to me like a poorly-worded email went out from OpenAI that didn't actually ask for C4 images, but one of Sama's employees interpreted it as an ask, and started collecting without raising any red flags up the chain. And they got fired for it.
