You can correct me if I'm wrong, but I believe the actual claim was that Zigbook had not complied with the MIT license's attribution clause for code someone believed was copied. MIT only requires attribution for copies of "substantial portions" of code, and the code copied was 22 lines.
Does that count as substantial? I'm not sure because I'm not a lawyer, but this was really an issue about definitions in an attribution clause over less code than people regularly copy from stack overflow without a second thought. By the time this accusation was made, the Zigbook author was already under attack from the community which put them in a defensive posture.
Now, just to be clear, I think the book author behaved poorly in response. But the internet is full of young software engineers who would behave poorly if they wrote a book for a community and the community turned around and vilified them for it. I try not to judge individuals by the way they behave on their worst days. But I do think something like a community has a behavior and culture of its own and that does need to be guided with intention.
