Naming servers something cute, witty or clever is a gold standard of freedom among engineers. When engineer perks (server naming, or free sodas/snacks/food, lax daily start-times, etc) are taken away, the good engineers will quit.
If you want to name servers after fairy tale characters and you will have a tantrum if management won't let you, then you are not mature enough to work for a company. It's called growing-up and being responsible.
And good engineers understand the value of memorable names, as well as the less tangible value of good corporate culture.
