Reading the article informed me that they are banning Coursera because universities are conducting classes on the site. That's not the case for wikipedia.
Additionally, said universities are referring to themselves as their traditional name (e.g. "stanford university") and not "coursera."
I seem to have missed this detail. However, why is it a problem if Stanford contracts out to some third party to operate a particular course? I enrolled in a local college a few years ago and took courses online. Not one of those courses was located within the college's web site- they were all third parties. Why would I have the expectation that the college doesn't vouch for the validity of the course material?
EDIT after reading the update: I read this as back to square one. Stanford is offering courses via Coursera for free. But Stanford doesn't offer free degrees. Why is that a problem?
MN's opinion seems to be its citizens can't get a degree online from a school outside of MN unless that school is registered with OHE. However, the quoted law speaks to not having a physical presence.
