You certainly did! But there are a lot of people who think "OSS license means there are no requirements" and think it's okay to do things like copy without attribution when the license requires attributions. I know you didn't say anything like that either, but some others might think it.
It seems to me an important question is, "is this like a human who learns from examples, or is this really a derivative work in the copyright sense?".I'm not sure how to answer that. I'm not a lawyer. I don't know if many lawyers can answer that question either!
Copilot isn't human and therefore what it does isn't a "work".
The usual issues still apply to users of Copilot - unwitting violations of license terms of the code it was trained on (like non-attribution) are still violations.
Whether or not the result is a license violation is tricky legal question. As always, IANAL.
