It's situational.

The blame on how the tool was used and whether this was negligence. If I hit someone with my car because I was looking at my phone, it's not the tools fault. If I hit someone because my brakes failed due to a manufacturing defect, sure blame the tool.

In this situation, the author didn't understand the API key they created. They also likely told the AI it could do a bunch of things (I have claude code ask me before doing anything except read/plan). So I'm sure he turned off some guardrails.

He expects an API to offer an "are you sure?" - it's an API.

He's blaming everyone but himself.
