I'm personally going to spend hundreds (likely thousands) of hours donating content to the public domain.
Other projects are all CC attribution, I think public domain is best for content. Code licensed under GPL.
Other projects are often not on GitHub, the place where technology actually happens. Our posts are written in markdown (mdx) so editing them isn't too bad. The embedded editor can also copy its configuration to the clipboard to help users modify existing editors within the source code.
If you look at the example blog post you will see that our method for running code in the browser is a really nice experience. We are first developing a competency in java/typescript education to attract the kind of crowd that can actually make edtech products within our technology stack.
I care a lot about my project but time will tell if it actually has any legs of its own.
