My bet is to reduce the competition from other MOOC offering sites. If colleges didn't offer MOOC's, then that model would stand in stark contrast to the traditional educational model. And when MOOCs showed to be effective and gained popularity, it would put the authoritative hold universities have on education into question. Now that they are leading the way in MOOC's, they can curb that authority building and reduce the dramatic contrast which makes their model seem absurdly anachronistic.
