Felleisen's entire goal with the Racket project has been teaching-focused from the beginning. I don't think anybody in the community doubts that he cares about teaching and evangelizing Racket.

The problem is that he has a very... how to put it. Matthias seems to believe that you must fight and struggle your way through academia and prove your worth to earn respect at even the most basic level. He is known for verbally abusing his students regularly. As I wrote elsewhere, I was explicitly discouraged from applying to Northeastern if I didn't feel I could withstand certain kinds of regular verbal abuse at his hands. That's unacceptable behavior, regardless of the "true intent" underlying it.
