I wouldn't expect an article named "The Dangerous Mr Kahn" to spend much type discussing the upside of the Kahn Academy. Going into it, it's obvious that it is an advocacy piece written by someone who's not thrilled with Mr Kahn's work.
The OP's point is that hn is a discussion forum, which is most effective when the discussions are somewhat balanced. But since the Kahn Academy is a darling of this forum, this article is here just to be knocked down, and anyone not joining in is likely to be downvoted. That makes hn less valuable.
