That response doesn't seem brazen. It sounds like they had a deeply mistaken understanding of what an open source license grants and believed it would be fine to use the name and branding as well as the code. Unless I missed it, it sounds like they are changing how their site communicates its relationship to the original source.

What I find baffling about that conversation are the people having their LLMs weigh in on what the author should have done. Verbal takedown by LLM is a new level of cringe.

Edit: There are some replies I hadn't seen, their confusion and request for patience sounds like they still don't fully appreciate their mistake.

It sounds brazen and incredibly entitled. The LLM response seems fitting for a vibe coded project with a vibe brain author.
