I think the core argument has much more to do about plagiarism than learning.

Sure, if I use some code as inspiration for solving a problem at work, that seems fine.

But if I copy verbatim some licensed code then put it in my commercial product, that's the issue.

It's a lot easier to imagine for other applications like generating music. If I trained a music model on publicly available Youtube music videos, then my model generates music identical to Interstellar Love by The Avalanches and I use the "generated" music in my product, that's clearly a use that is against the intent of the law.
