Exactly, but the kinds of things that Copilot is taking are necessarily very generic. It’s not going to be taking the “special sauce” from an open source project, because that is very unlikely to be the most probable continuation of any prompt that would occur in normal usage.

Copilot is taking things like “reverse a string” or “escape HTML tags”, that have very little originality to start with. This kind of common language is analogous to the musical motifs that have been also found to be under the threshold.
