Now I'm not sure how a course you don't have to take and can leave at any time could be called a "tyranny" but I'll deal with the question raised in this post head on: "Are we are attempting to impose our values (of openness, sharing, online learning as the future of education, etc) without a critical examination of what that means for practice and for individuals who are part of social organizations?" And the short answer is: no. For two reasons. First, nobody's imposing anything here; if you want to go back to your structured formal education, where you pay a substantial fee, there are thousands of institutions who would be happy to help you. Second, the openness (and the rest of it) is the result of a critical examination. As I have argued with respect to the principles of successful networks, if you want your social organizations to be effective at all, you need to embrace things like autonomy, openness, interatcivity and diversity. We select these principles, not because we're arbitrary, but because the best evidence tells us they work.
