That's certainly good but you can't get an MIT degree with Open Courseware, so it's not providing the same value that being a proper student does. I don't see how having more of the best is a capitalist thing and not generally good no matter how you look at economics. It's not about MIT gaining market share, but about them giving better education to more people so the overall good to the students is higher. Perhaps there's a practical reason - maybe they can't find enough professors of the quality they want to teach any more students, but last I heard, professors weren't in short supply, especially not when you have $15 billion like MIT does.
