Since all the lessons here are CC BY-SA, anyone, Khan Academy included, can use them as long as they keep them open. I’m also aiming to build this project in a way that it doesn’t really need me to stay alive. It’s a static site with no servers or accounts, so it costs almost nothing to run. If by any chance I ever stop, anyone can copy the repo and keep it going, lessons included. That’s kind of the point of making it open source.

I agree. I’ll make the modifications later. Thank you.
