Because that's what the Corporation Suits expect us to call ourselves. If I dress and act the way they expect a Hacker to dress and act, They will leave me alone and won't try to promote me. I have the people-skills to do the job, I just plain don't want to be a manager. I have, in fact, once issued the threat "If you promote me, I will quit." Don't try to call down on the Old man, he been playing the game longer than you have, and he may not be bluffing..... (Yup, they did, and I did; the same day.)
