> Would you - or your employer - want to risk a lawsuit because you inadvertently copied code that's actually released under a license with particular terms of use?

Copilot doesn't do this unless you bait it with very obvious prompts. But to answer your question: yes, never worked at a company that actually cares about licenses. It's a mirage. No-one ever gets sued. If your code is out there it will be used and abused and everyone gets away with it.
