You say it's a copyright license, and I think that's exactly where I'm struggling with this. My understanding is that this is a license for something copyrighted or otherwise protected. Copyright protects things from their creation. A copyright license provides certain people action that would otherwise be denied by copyright. So are you saying that your understanding is that what we write here on Lemmy is copyrighted, with authors holding the rights? That would be helpful to know because that has not been my understanding of copyright (and I know country plays an important role here), so that would be interesting to look into.
