He is fighting a losing battle. That's why nobody in the administration cared. Academic integrity already doesn't exist anymore. As Nassim Taleb would say; there are plenty of highly educated idiots with PhDs.

Even the idea that MIT is somehow better than some other universities is itself a fiction. People are conflating financial success with academic ability. The former is mostly the result of social connections which are formed within the academic institutions and have very little to do with actual capabilities.

Universities should just sell degrees for a high price without requiring the students to attend. If they're rich enough, their skills aren't going to matter anyway; they'll succeed in their careers regardless so the university will still look good. 'Academic integrity' will be intact. Especially true for business, economic degrees or other humanities.
