Principles be damned, there is money to be made!
Stanford's total enrollment is about 20,000 students. $35,000 per year = $700,000,000.
Offer 16 new online courses which yields 20,000 students per course taking a $99 final exam. $31,680,000. Less than 5% of annual tuition-based revenue. That's a new library without hitting the endowment fund, underwriting existing salaries, funding pension obligations, or adding a new facility dedicated solely to the production of online educational content.
I think Leland and Jane Stanford would be proud to know that the memorial they built to their son is today moving in the direction of educating millions worldwide.

These classes are also highly vulnerable to cheating and you can be sure that a large number of people will take advantage of this to pump up their resumes.
