@hynek @sirosen The legal stuff in that AI policy isn't sitting quite right with me. I understand the concern with the legal status of AI generated content but I think the menu of outcomes here is probably some combination of:
1. AI generated content is owned by the person who wrote the prompt
2. AI generated content is not eligible for copyright
3. AI generated content is owned by the model owner (or the model itself??)
4. AI generated content is a derivative work of its training data and context
If it's 1 or 2 you are fine because 1 is equivalent to hand-written code and 2 is equivalent to incorporating public domain code (modulo jurisdictions that CC-0 was created to address). 3 is probably also fine because it's roughly a work for hire.
Scenario 4 means that those contributions are derivative works of a combination of a bunch of GPL and proprietary works and the contributor doesn't have the right to offer it under a less restrictive license in the first place, so "you take legal responsibility" doesn't seem like it helps the situation. If you are asking the contributor to indemnify you if it turns out they had no legal right to contribute and you get sued by someone claiming attrs is now a derivative work of their material? If so you should probably be explicit about that.
Would it be valuable for me to comment about this in the issue / PR?
