Intentions and Consequences

While it is true that people can have some intention when they create things that does not explain natural events.

Cause and effect logic only applies to a small subset of events in the world.

A lot of things came to be as a coincidence without any clear intend of everyone involved. Other times some sort of compromise middle ground solution have emerged from actions of people of conflicting interests.

There is also a issue of outcomes not matching the intentions, because the original creator was inept and could not understand the outcome and consequences it will cause. Often even when you know all there is possible to know the outcome will not be as intended simply because it does depend on probability you do not understand. Especially so if it involves other people. People have free will and will not always do as you want them to.
