Let's say I have 25 line function which does something novel and can be published as research (which I did, BTW, no joke), and I opened its reference implementation with AGPLv3+.

Is it again too trivial?

is 25 lines the limit then? do you count comments? can I codegolf a few lines to get below the limit?

> is 25 lines the limit then?

I don't know. That's my function's length.

> do you count comments?

No comments, no blank lines.

You bet. But, if you copy my reference implementation, you need to get the license as well.

However, the research is on the open. Read it, implement it. That's no problem.

But, CoPilot is not reading my paper. It's reproducing my function verbatim, which is under a license which has share-alike mechanics.
