I share your position on the Subject. I cannot respond to what is "not true" as I don't know to what the statement refers; nevertheless, I have evaluated teaching online in different scenarios----some controlled by variables you mentioned in your response, and I have solemnly concluded that if I were to fulfill my obligation as an online instructor, I see myself spending a significant number of hours higher than in a classroom environment when so much can be achieved in a group environment in a shorter time.
