Can you post the actual link of the repo? You'd get responses with more context.

You had commented on the photocraft post prior, so if it's that, then it's a bit muddled. It's a LLM based re-implementation and not a copy of the code made open. So the argument would be weaker there, and you'd really need specific code samples to make a case of copyright infringement. Photocraft not "piracy" as is normally understood, which is the exact same binary, optionally with the license protection removed.
