This is half true. People will go out of their way to make the organization better if it make their jobs easier (ex: switching to more modern easy-to-work with technology). But if for instance the project is going in a wrong direction, most of the time you have no good reason to fight to change things (and yes, it's fight b/c often it's about changing opinions and demonstrating repeatedly that things needs to be done different). So sure, do your duty and voice your concerns but at the end of the day just go with the way the boss decides. This is called delegation of responsibility and something a lot of people don't grasp. You need to cover you ass to stay sane.
