I'm not a lawyer, but why do all the other big companies filter their LLMs then? I really think that people would use it for bad, and people would at least try to take legal action against those creating/hosting the model. Not that they would lose, but it seems like there would be legal annoyances to deal with at the very least if they don't filter their outputs.
