I'm not sure if we see a return of the MOOC or just growth in various alternative formats, because the term MOOC actually has a very specific meaning which is not always reached by the services/companies mentioned in the article.
I would for example consider Pluralsight to be just "Online Courses", and the price tag on Udacity's nanodegrees makes me wonder whether we can consider them to be truly open (I attended university in The Netherlands where the cost of tuition for a year is lower than the cost of doing a $200/month nanodegree at Udacity for one year).
