The author's complaint seems to be that the Khan Academy's history lectures give an overly simplified view of history and that this, along with their availability, will make them more attractive to students who, the author fears, will watch Khan Academy videos in lieu of studying the topics in depth. This, he fears, will lead to a cultural forgetfulness of what the author considers to be the important moral lessons of WWII.
It's an important objection. There is a real tendency towards laziness among human begins and an easy availability of a simplified history could discourage people from deeper study. A simplified history from only one viewpoint is even worse. But I think he's pointing the finger in the wrong direction. Wikipedia is already a far greater threat on that matter and their are plenty of simplified versions of history available, some even taught in schools. Sal is only example of this (and possibly a product as the author alludes.) The proper solution would be more, and more in depth videos from other perspectives. I know some people who might be willing to do just that...
