That's a strange non sequitur. A statement against Waterfall is not a statement for Scrum (no reason to shout, I get that you don't like it but shouting its name is weird). Please, point out non-trivial successful (delivered on time, on budget, and with all initially planned features) Waterfall projects that did not modify Waterfall into something sensible (that is, incorporated feedback loops and probably executed as a series of iterations rather than one 5-year long project with hard distinctions between each phase).
