Nice point But let's be real. Today business it's all about the money. So every MOOC platform needs money, they're selling knowledge. Open2Study is great by that mean, it's MOOC in real sense. They're providing you with free coursers (limited knowledge) but if you want to expand it you must consider their college program. As I said earlier, term MOOC is great, but everyone is depended on money.According to Wikipedia MOOC means massive open online course. . . . The term MOOC was coined in 2008 by Dave Cormier.
Neither Edx nor Coursera is Open in the sense Dave Cormier meant it (open is "knowledge" constructed in open and free discussion between equal participants -see Habermas: Hershaftfreie Dialog - ), so when you want to get fussy about what Open really means, the correct answer is that neither Edx or Coursera did implement Cormiers idea of what a mOoc should be. Both got the concept completely wrong, they turned the concept on its head. Coursera and Edx are not implementing MOOCs, they are implementing anti-MOOCs (for more see my: what is an anti-MOOC)
