> The answer is obvious: sharing the prefiltering solution we used in this analysis to detect overlap with the training set. When a suggestion contains snippets copied from the training set, the UI should simply tell you where it’s quoted from.

If Copilot is reciting pieces of GPL code (which we know it can), then not only does it need to point out where it has grabbed that code from, Copilot itself is (probably) required to be GPL-licensed.
