I would imagine there's a significant selection bias at work here. This is not a random sample of students, and I don't think it's super odd that many of them get As. Perhaps more get As than should, but I'd look at the grade distribution of a less discriminating institution if I wanted to get huffy about grade inflation. Especially with no meaningful data in the article about historic grade distributions at Harvard.
