I think you've hit the nail on the head. I've seen this behavior from others in the space before too, it's not a one-off. They refuse to use LLMs themselves, and state as much publicly "I simply don't need to resort to using the slop machine, my skills are superior", yet FUME when others they deem as "lesser" are able to use it to achieve the same results as them, oftentimes faster.

I can guarantee this post would not have been made had he not been the one to find that vuln first.
