It is when someone wants to have something implemented because it was "their idea" and not because it is a "good idea" (an idea that logically matches other human beings' experience and needs when using a product).
I think the measure of how much a company has a user-friendly interface can be sort of an indication to how much the company is run by ego, and an environment where employees walk on eggshells as to not threaten anyone's ego, rather than be free to express good ideas.
