I have never understood the "it's not _your_ network, it's the "_the company's_ network" diatribe. Folks who say this _NEVER_ apply the same logic to their own job. Why is that? Do you refer to things that you are responsible for as "yours" or do you always refer to them as "the company's"? The personal pronouns indicate responsibility, not personal ownership.
IT is there to support users, but not just users. There are always constraints like them or not. Sometimes IT must "dictate" in order for things to actually work and be sustainable. Sometimes users want things that simply cannot be done with the resources available.
