It seems you are desperately trying to make a strawman without any sensible argument, i don't personally think it is "snarky" to call things as they are, plain and simple, you, as supposed expert and professional academic, post a blog on Nature crying that "ai stole my homework", it's only natural you get the ridicule you deserve, it's the bare minimum, he should be investigated by the institution he works for.
A reasonable amount of AI use is certainly acceptable, where "reasonable" depends on the situation, for any academic related job this amount should be close to zero, and no material produced by any student/grad/researcher/professor should be fed to third party LLM models without explicit consent, otherwise what even is the point? Regurgitating slop is not academic work.
