If one court allows this and there is a rush to sue other prominent artists and content creators, then it could result in a whole new body of law in which this becomes accepted. And then we could start seeing it bleed into criminal law as well. Criminal protections are much stronger, even having a constitutional connection, but there also is a long history of state laws and common law on the civil side that is being ignored here, so who knows? The law and how it is interpreted can change over time. And that direction isn't always pretty.
