Sounds like an opt-out dark pattern. US law is unbelievably aggressive when it comes to issues of copyright, and makes copyright itself opt-out, i.e. everything you produce is copyrighted, and you have to license it in order to remove that automatic copyright. But when it comes to building these models to reproduce imitations of other people's work, suddenly copyright gets loosey-goosey. Notice that it's a legal posture that implicitly condemns Copilot, which ignores explicitly formulated opt-outs in the form of licensing.
