I think it needed to be said because I really don't see why.

LLM are excellent translation tools. Nothing is learned or stolen from them out of this exercise if this is a copyright issue you are getting at.

Then Rust? Why picking on it, the language is morally corrupt? In what way? If it were a rewrite in Object Pascal it would be better?

Help me get the argument please I might be dense: is the rewrite unethical or the llm use or rust or any of the combinations?

The fact that it's less C++ and more rust makes it more trustable and more ethical, not less.
