CUDA and CUDA compiler (proprietary vs open-source)


I came across interesting information in a professor's lecture slides. Some information on them got me confused:

1.) In one of his slides, it says: "CUDA has an open-sourced CUDA compiler": https://i.imgur.com/m8UW0lO.png
2.) In one of the next slides, it says: "CUDA is Nvidia's proprietary technology that targets Nvidia devices only": https://i.imgur.com/z7ipon2.png

AFAIK, if something is open source, it cannot be proprietary as only the original owner(s) of the software are legally allowed to inspect and modify the source code.

So, the way that I understand it is that the technology CUDA itself is proprietary but the compiler is open source. How does this work? I don't understand exactly how the technology can be proprietary while the compiler can be open source. Isn't that self-contradictory?
