UPDATE: According to the WSJ, Apple has contacted Fiore:
Apple called the cartoonist Thursday and suggested that he resubmit the app, Mr. Fiore said in an interview. “I feel kind of guilty,” he said. “I’m getting preferential treatment because I got the Pulitzer.”
Preferential perhaps but not uncommon. Several controversial app rejections have been reconsidered when publicity brought them to the attention of higher-ups at Apple. Unfortunately, the "review team rejects, executive team reconsiders" is not a scalable or likely desirable strategty for Apple.
