Narrative:

We were inbound to ZZZ on an IFR training flight. We heard the citation call that he was taxiing; and gave calls 10 miles out; 6 miles out and 3 miles out. As we were approximately 1 mile out; the citation called takeoff; and without any hesitation or check; rolled onto the runway. By the time we realized what had happened; there was less than 30 seconds to respond. We applied power and went around; turning right as the citation was now taking off directly under us and we could no longer see him. I suspect that had we been there 20 seconds earlier; there would have been a collision. The pilot either did not check or assumed that he could force us to go around to [avoid] disturbing his commercial passengers. An aircraft through his roof probably would have disturbed them quite a bit. Whether this was egregious bad behavior or egregious lack of care; it created one of the most dangerous situations of my aviation experience.
