Good and important point about educating developers. Maybe it goes even further and similarly to planned EU regulations, products based on black-box AI models need to have documented behaviour. So the documentation needs to include explicit hints about generated code being unsuitable for clean room engineering and has to be considered "tainted" one way or the other. I don't worry about verbatim reproductions at all, because results of that nature can easily be filtered out if need be (or be annotated with the proper reference). I'd expect a company that also runs the 2nd biggest web search engine to be able to pull that off with ease.
