As someone who attended CMU, who has seen friends flunk out, and who left voluntarily myself, I have to say that its administration has no problem flunking out someone who contributes directly to the bottom line. From what I gather they have a pitiful endowment & low alumni contributions* so tuition actually winds up paying significantly for undergrad courses.
(*MIT students joke about hating the place. A not-insignificant number of CMU students really do.)
I applaud Phil's actions. If nothing else, a tuitionless school would remove a significant barrier to success: The stress of knowing you're bankrupting your parents, making good performance all the more necessary. I know it was so for me. I bet it was for a lot of the people who killed themselves
