Jeff Bezos once warned to "avoid proxies" and using fake scrum is a prime example. Scrum on its own is just a proxy for agility. Scrum done correctly can give you great agility. If you're running stand-ups and using a backlog but are unable to iterate quickly and deliver incremental value then you're failing at your actual goal.

Of course, agile itself can be considered a proxy because the ultimate goal is always customer value.
