Quadratic's source code is openly available on Github, we will amend our language to "open access" going forward. We are far more open than any other spreadsheet, and pride ourselves on that!
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
Your source code is not “openly available” simply because you have published it.
