I think the moralities of all the big heads in AI are questionable. The training corpus is largely stolen, and they are all in inescapable debt but keep going. But at this point, their products are so useful that almost nobody is willing to sit back and wait for a "morally acceptable" LLM to come around (which would inevitably be inferior).

I can't comment on CSAM though - if X.ai really is "okay" with it then I'll agree with you that they're more immoral than the others.
