Define policy forbidding use of AI code generators

I understand where this comes from but I think it's a mistake. I agree it would be nice if there were "well settled law" regarding AI and copyright, probably relatively few rulings and next to zero legislation on which to base their feelings.

In addition to a policy to reject contributions from AI, I think it may make sense to point out places where AI generated content can be used. For example - how much of QEMU project's (copious) CI setup is really stuff that is critical content to protect? What about ever-more interesting test cases or environments that could be enabled? Something like "contribute those things here instead, and make judicious use of AI there, with these kinds of guard rails..."

There is a well settled practice in computing that you just don't plagiarize code. Even a small snippet. Even if copyright law would consider such a small thing "fair use".

This isn't 100% true meaning it isn't well settled. Have people already forgotten Google vs Oracle? Google ended up winning that after years and years but the judgements went back and forth and there are around 4 or 5 guidelines to determine whether something is or isn't fair use and generative AI would fail at a few of those.

Google vs. Oracle was about whether APIs are copyrightable, which is an important issue that speaks to antitrust. Oracle wanted the interface itself to be copyrighted so that even if someone reproduced the API from a description of it, it would infringe. The implication being that components which clone an API would be infringing, even though their implementation is original, discouraging competitors from making API-compatible components.

My comment didn't say anything about the output of AI being fair use or not, rather that fair use (no matter where you are getting material from) ipso facto doesn't mean that copy paste is considered okay.

Every employer I ever had discouraged copy and paste from anywhere as a blanket rule.

At least, that had been the norm, before the LLM takeover. Obviously, organizations that use AI now for writing code are plagiarizing left and right.
