The reason they do it is because it's the New Yorker. It's their house style. It's what their readers expect and understand and it has become a tradition and perhaps even emblematic of the magazine and its brand. Complaining about the "pretentiousness" of the New Yorker is like complaining about the convoluted commands in eMacs or vim - it's not a problem, it's a feature.
