I can't speak for Jimbo, but if I were in his position I would consider it an obligation to enforce the integrity of wikipedia in extreme cases like this, in spite of any disproportionate controversy that may possibly result from my actions. This seemed like a clear cut case of administrator abuse to me (I'm a centrist; no bias accusations please). Most of the small handful of people who know about this controversy will forget about it within a week or month. The article, on the other hand, would be lost forever; the knowledge therein stolen from innumerable potential readers. Think of the bigger picture, and moreover, consider these overreactions and what they implicate.
