Glib clichés never have convinced me of anything.
I've been working for a user experience team for a major software company for years, and we encounter this sort of mindset often. But, since we're in the "strategy & planning" group, we influence the improvements of our products on many levels.
In many companies, the maiden voyage build, version 1.0.0 is always dearly loved...and dev teams cling to it like their beloved blanky or teddy bear. They fear change.
User interfaces should never be designed by users, developers or stakeholders. An objective user experience team with human factors psychology is the best unbiased way to move forward in the competitive world of software.
