Everyone points to the four "preferences" part of the manifesto and ignores the more important first paragraph, and the far more important second page ("principles").
Key phrase: "We are uncovering better ways of developing software by doing it and helping others do it."
That's different than "we are cementing our idea of software development process by teaching it and certifying others to teach it." It's different from "we are making people feel better." It's different from "we don't write documentation" or "we force velocity as high as possible"
If we lose that key phrase, we lose it all.
