Copyright laws, if enforced perfectly, would make programming simply impossible. We've been skating by on people not really enforcing them, despite the laws still being on the books, and the existence of tools like this makes that not a viable strategy. Today it's Copilot, which can be shut down, but tomorrow it'll be something developers can run at home. Bits don't have colour; there's no way to distinguish between a copy happening by independent recreation, and one that's actually a copy. So we'll need proper rulings.
In fact, considering Fauxpilot, that will happen as soon as the models have improved somewhat.
*: Of course I don't think "independent recreation" is really a thing. Humans are excellent at open source laundering. It's called "learning".
