If storing code in a text file and copying the file doesn't magically remove copyright, and compressing it in a zip file then decompressing it doesn't remove copyright, it seems likely that embedding it in a state machine to be retrieved with the prefix of the original file doesn't magically remove copyright. Even if it's slightly corrupted in the process.

If you wanted a copilot style thing that doesn't print out GPL'd software, you wouldn't feed it a load of GPL'd software for it to remember in the first place. What we have is like doing a clean room reimplementation by loading the original in your text editor before you start and deleting parts of it at random.
