I did an interview a couple years ago when Corgi was first hiring engineers. Nico and I ... did not click and it was probably the least smooth interview I've ever had despite it just being a phone screen.

I wouldn't be that surprised if Nico genuinely thinks "we didn't copy the code" is a reasonable defense. It would be a clear cut rule, and extreme "shape rotator" types often have trouble with the fuzziness of things like law. In reality, copyright infringement is often more like the porn test, you know it when you see it.
