Help

It is just difficult to offer help when someone does not want to be helped. Those who care will get frustrated, and those who don't will pushed.

In various group settings I have seen the same issue.
When one doesn't realize the problem, then one is the problem. Or somebody would say something like "if you are not a part of the solution, then you are a part of the problem".

But most people don't realize that. They just focus on their own domain, their little comfortable space and avoid having their views challenged. Or they get defensive quickly. In the end, what is the result?

This may not be a necessary factor for failure, but all the failed projects have this.
