Is that across all universities? Because I would guess that, for example, University of Illinois gets a much larger portion of its funding from government sources than University of Chicago (which would be one of those well-endowed universities which, incidentally, just cut tuition to zero for undergrads from families making less than $250K).
Personally I've never had real people use any of my personal projects, just some bots trying to break into the server occasionally with some generic scripts. So you'll probably be fine
