From my limited experience working at IBM (7 years ago I interned for a little over a year), I think you're right. A lot of what the author writes is absolutely true, but I think he underestimates the power of a few good teams to lift the company out of something like this.
I've had an app rejected from the selector search the article mentions. As the article says though, I'm sure it's within apple's power to ignore them, especially if lots of existing apps use it.
I really respect what Sal Khan is doing. I think his methodology for creating videos and exercises great because of how adaptable his process is, and how he gets creators who have real teaching experience to create the content.
That being said, it makes me a little happy inside that the company I work for addresses the specific criticism in the article, although it doesn't go to the lengths that Khan Academy does in terms of video and more interactive exercises:
This weekend I implemented an idea inspired by the feeling that the articles I'm reading are all coming from the same viewpoint: A reddit aggregate that interleaves articles of different political opinions.
It turns out reading ideas from different political viewpoints without someone to put it in context gives you a lot more misinformation and heresay than actual facts.
The site is here, although my webhost seems to be acting up at the moment. http://grainofsalt.info/
