> But nobody cares if you copy a nice code pattern from a GPL code and apply it to your own code base

this is not true, smh. See Oracle vs. Google.

[int_19h]

Oracle v. Google involved actual Java (declarations) code being copied; that it was a derived work wasn't seriously disputed there.

CoPilot will return actual GPL code verbatim.

[int_19h]

Yes, and that's why I personally believe that the model itself should be considered a derived work of such code. But OP was specifically talking about "code patterns".

[endisneigh]

Copying the code verbatim would fall under copying the code pattern. You talking about changing the name of the variables or something?
