Sure, because "flipping the classroom" still requires a classroom and that, IMO, is what some (politicians and people who don't want to spend money on schools) disregard. I feel KA may have a hand in changing the quality of education, but I don't think it will do it alone. The criticism, IMHO, is sound. It may lead to baking education[1] in some schools if not done correctly.
