I think it's hard to say one way or another. My guess is the latter, or perhaps the audience isn't even aware it's vibe coded.

I (like many other software folks) are aware of AI-isms in writing, so when I see something that it so obviously AI generated in a project, it's equivalent to a giant red waving flag.
