Khan Academy is honestly the greatest among the great educational videos out there, so great that another platform steals its videos.  In the Philippines, where I live there's an organization called "star books" basically an application to provide free educational books and videos similar to Khan Academy but I was skeptical unlike Khan who makes their ORIGINAL videos, star books get videos off the web and upload it on their app which got me wondering do they not get copyright? Then I found Khan's videos uploaded there, even though Khan Academy is a non-profit organization and provides free videos, I do not know if Khan agreed for its videos to be uploaded there. Educational organizations still have the right to decide whether their videos be uploaded or not.  

Worst part is they may be profiting off it, Im not sure since the videos are still free.
