I've started uploading some of MIT's OpenCourseWare to FBXL Video, our peertube instance.
In particular, I started with Professor Lewin's incredible 8.01x and 8.02x science courses. These lectures are simply THE reason I was able to pass college level physics.
Incredibly, OpenCourseWare was knocked off of Youtube for TOS violations for a time! I want to make sure they're available whether or not some big tech lackey thinks it's worth hosting. It was just a few gigabytes to host hours and hours of courses, so anyone else running peertube instances should absolutely consider mirroring similar content!
