The guy who wrote Winamp Sold it decades ago. So you should clarify who is defensive about their code :-) The original coder is really good - he also wrote the awesome AVS visualization plugin for Winamp which among other things utilizes a special programming language called “eel”. After selling Winamp he went on to create Reaper which also uses eel I think.
“Meteor” by Dan Brown (could be a different name in the original language). It was the first time I read something that was bad. Up until then book were cool and fun and interesting. It was a puzzling experience.
Edit: it’s called “Deception Point” in the original.
