We now note that that we do not waive our attribution requirements for Spritely Goblins, which are present in Apache v2 (and for that matter, CC BY, CC BY-SA, and most FOSS licenses) https://codeberg.org/spritely/goblins/pulls/998/files

So if you train on our codebase, you have to retain attribution, which we consider the most important requirement to motivate development of technology in the commons.

If, somehow, you are using a statistical soup which has no way to preserve attribution, well, we don't permit or approve of dropping such a requirement, and actually, the licenses we use never have.
