At no point in this process does the author seem to stop and inspect the results to see if they actually amount to what he’s asking for. Claiming that this output represents a decompilation of the obfuscated target seems to require at least demonstrating that the resulting code produces an artifact that does the same thing.
Further, the claim that “Using the above technique you can clean-room any software in existence in hours or less.” is horrifyingly naive. This would in no way be considered a ‘clean room’ implementation of the supplied artifact. It’s explicitly a derived work based on detailed study of the published, copyrighted artifact.
Please step away from the LLM before you hurt someone.
