The thing is, there is a ceiling with SaaS products. You can usually hit it within 5 years of starting. That ceiling is entirely controlled by churn, with 0% churn, you go to the moon, but nobody has 0% churn.

Once you hit that ceiling, the only reasonable thing is to focus on churn, not growth (as it will have the most impact). But that is like explaining that a "circular line on a map is actually a straight line" they say they get it, but they still see a circular line.
