What we're seeing here is that universities have realised that you can't sell content and that the business case for MOOCs is selling credentials, verification and examination. The article mentions that the other MOOC players, edX and Udacity, are also selling proctored testing of students at local test centres. Learning is free and open but if you want credentials and other add-ons then you will have to pay. However if the total costs for this path is lower than the full campus experience then we have succeeded in opening up education to more people. That's the benefit in my opinion.
