I think once they have something mature enough to productize, they will do so. Basically every online consumer service ever started free and stayed that way until enough people recognized its value. There's definitely enough value here to do so -- people will start to discriminate between professors and course designers -- but as a platform there is no way it is mature enough for anyone to give themselves that much of a competitive disadvantage. We are still in the "Mad grab for market share" phase of online learning.
