This is the exact same kind of shit that got thrown at every person ever who successfully challenged a rusty status quo, especially when job security was at risk. Quoting the original piece in Washington Post:
We have great respect for the stated goal of Khan Academy — “A free, world-class education for anyone, anywhere.” Yet, we have some serious concerns about the quality of the instruction providing this education. Indeed, if either of us were supervising Khan’s instruction, we would point to some concrete and important gaps in his practice.
The key is "if we were supervising". That's the real problem. That someone is making something huge happen, and they are not playing a role in it. Guess what - nobody is stopping this guy or anyone else from producing a few hundred of educational videos with great content and making it available for free. However, some way or another, the people who are capable of a stunt like that are much fewer than those who can hate things on the Internet.
