Why do some teachers bash on Khan Academy?

From what I’ve used of it, it’s somewhat hit-and-miss. I do recall a couple of occasions where KA lessons fell far short of the same thing in a classroom (with a decent teacher), and I’ve yet to see a video there that can surpass a lecture from a good teacher.

Additionally, much of KA is, as with any online curriculum of that sort, about memorization. KA practice feels like online math homework (which of course it is, essentially); I’ve never had it come close to what a math test is like (the kind where much of the credit comes from doing it right, in addition to getting the right answer).
