The term you are looking for is “source available”. Using “open” is deceptive.

Your source code is not “openly available” simply because you have published it.

linked in the github issue: "Quadratic's source code is available publicly in this repo. However, we do not provide any license to use, modify, or distribute our code." so you can look at it but dont have permission to use it
