Harvard (the University, not it's alums) has had a near nil presence on K-Street for a looooong time - and their primary lobbyist with the GOP has been on Trump's bad side for sometime after he pissed off David Sacks.
I'm also an (severely disillusioned) alumni of some of the student orgs that are mutually using Harvard the institution as a punching bag to fight their culture wars.
A lot of this is honestly very childish BS done by some petulant alums who were already dicks on campus.
There is very little campus loyalty at Harvard which makes it easier to use it as a punching bag for your culture war (whichever way you lean).
