I find that very few people and even fewer institutions are consistently always on the right side of things morally, even in very clear-cut cases (never mind that what exactly the "moral thing" is, is a whole discussion in itself). It's probably better to look at the overall pattern rather than a incidents (either good or bad).

I have no opinion on Harvard myself by the way; I don't know enough about it. I'm just saying this is not an especially good criticism.
