An interesting thing to think about is if they would apologize if this wasn't published in a blog and discussed online.
Let's say Jeremy just walked away quietly in disgust and didn't say anything publicly. What would have they done? I would guess that they would have chucked it under "We did a great job enforcing the code of conduct. Problem solved".
I know a lot of Hacker News users don't like it, but fact is that getting to the top of Hacker News is often the most-successful driver for getting something fixed in the tech industry.
This might be going too far, but Type A personalities don't realize they're being shits. This allows them to get things done, as they don't care very much about what other people think; but sometimes it means that they deliver solutions/products without much empathy for the end users and the individual contributors who made it.
