There is a world of difference between metal music making teenagers satanic and an LLM giving explicit, detailed and actionable instructions on how to sexual assault someone.
I'm not sure lack of instructions ever was an issue, and it seems very strange to think that the existence of instructions would be enough of a trigger for a normal person to go and commit this type of crime, but what do I know!
But this isn't about normal people. It's about people who maybe easily susceptible or mentally impacted who are now provided with direct, personalised instructions on how to do it, how to get away with it and how to feel comfortable doing it.
This is a step far beyond anything we've ever seen in human history before and I fail to see Google's behaviour being anything less than appropriate.
