"Talking about ‘clean code’ was more along the lines of ‘clean clothes’ or ‘spring clean’ than ‘clean eating’ or ‘clean desk policy’, with their justifiably negative associations."
Huh?
In what way does "clean eating" or "clean desk" have "justifiably negative associations" ?
In fact, I don't think I've ever heard the term "clean eating" used before... I wonder where that term is commonly used?
