An intrim update to Copilot could link to where the code as pulled from. Or maybe there's a way for open source devs to add a comment to the code that links to their community/repo. If it was standardised then any data gathering would need to follow the collection rule.

I agree with the article's long term outlook about community and code quality, it is a very long term outlook though. It makes me wonder if humans will actually be writing code.
