I had read the post [1] here on HN at the time, about how he faced abuse in the Racket community, but when posting this submission I did not recognize the author of the book was the one.
I'm glad his work hit the frontpage. This would hopefully attract more attention to his work, as well as the problem in the Racket community, if the problem still persists.
After that piece appeared on HN, Racket leadership posted an apology [1] but didn't announce any changes to their policies or procedures to prevent the issue from recurring. In particular, there were no consequences for the person in Racket leadership who had committed the abuse
Matthew Butterick's work is pretty well known within Racket and has brought many people to the language.
I found it sad to read he had been bullied by Matthias Felleisen and as a consequence no longer contributes to Racket. It is a big loss, and I hope something can be done to bring him back.
