The point of the system is what it does.
They can't just say "we don't want to deal with small timers who will not pay us big bucks doing nonstandard things" without pushback but they can write the policy so that a huge fraction of those use cases fall into some crack that can only be got out of by incurring the kind of expense that's a non-starter for those users. Your municipal code is rife with examples of this.
This is a catchy aphorism, but not really true. Things can be badly implemented so that they fail to achieve their purpose.
People often have trouble with this saying, and that trouble often boils down to the difference between intent and purpose.
The people who create a system have some intent for it. The system may or may not effectively achieve that intent, may or may not outlive the initial conditions that surrounded its creation, and may or may not have side effects.
Purpose is something humans assign. It is sometimes linked to intent. A carpenter's hammer is intended to drive and pull nails, and that is often also its purpose. The purpose of the hammer I keep in my basement is breaking open walnuts.
The phrase is stating that the purpose we should assign to systems when judging them is their outcome, and not the intent behind them.
Sometimes intent and outcomes matter, but the aphorism is simply not a good guide to understanding reality. It should be discarded.
The classic example is a hospital for treating cancer patients. Suppose that one third of the patients are successfully treated, while the other two thirds die of their cancer. Is the purpose of the hospital to kill two thirds of the patients? Clearly not, but that is the outcome.
