Helping people become better is good but just insulting them needlessly is silly. The rest of the article is good and helpful because it goes into what they actually did wrong but calling them bad programmers is insulting and doesn't actually add any value to the article (I actually think that it takes away from the article somewhat because of the tone it creates).
