Yeah... criticizing code is one thing (perfectly acceptable IMHO), but turning it personal made him into an asshole. Note that of course there's an element of "uncomfortable truth" to this—evaluating programmers' ability is probably a good thing, and he's right to a degree. We all know amazing and experienced programmers who write libraries that are like diamonds in the rough compared to other coders' work, but 1) you have to be tactful; you don't put people down for their code no matter what, because 2) you have to help them get there, and negativity is not how you do that.
