    Calling prompt injection "not malware" … is like saying a phishing email is not [malware] …

I would say phishing emails are not malware, I think most people would agree that phishing emails are not malware, and if pressed to defend this point on its own merits I would say something like “they are deceptive instructions that rely on a human executing them to do harm”. I think the “phishing” analogy supports the case for not calling it malware (it is a different, also bad thing).
