Also, Python is a much more practical choice than Scheme, and has technical merits which are at least as attractive as Scheme, and arguably more so. Scheme is elegant. But Python is also elegant, yet more practical. From that angle, looks like a net change for the better.
MIT also strikes me as a school oriented more towards producing engineers rather than programmers. And if you're going to school at MIT just to get into a career in programming, that sounds like a terrible waste of money. Robotics or electrical engineering? Probably a good choice. But programming? Come on.
Then there's the whole argument of why anybody needs to go to MIT, or even get a college education in CS. We live in a world with the Internet and scads of free books in libraries and documentation online. Follow that line of thinking and the whole controversy over this tweak in some random school's class content seems silly. It is as if nobody can learn anything outside of a class, so if it is not taught in that particular class at MIT, it will never be learned, and the world will end. Hilarious. :)
