But, yes, totally free content is somewhat limited at this point and, generally, MOOCs have to be seen as a disappointment to anyone who saw them as a radical free substitute for a university education.
Perhaps interestingly, when OCW launched, MIT presented it as very much not a substitute for an MIT education but rather as raw materials for educators to assemble their own courses. Which I'm sure was at least in part a matter of internal politics but still. (And, of course, ubiquitous video of lectures wasn't a thing at the time anyway.)
