As a staff member and grad student at USC I can tell you, internally, USC does not like or tolerate criticism of USC, the "Trojan Family," or really anything connected to the University. They act genuinely surprised and shocked when someone questions the culture of USC. Which is why the sexual abuse at the student health center, or the drug use by the med school Dean carried on for so long unchecked. Former President Nikias, as Petros said, only cared about fundraising. Not ethics, or even abuse of the students, just $$$. People were too scared to speak out against the president and powerful deans.
But Petros dared to criticize the elitism and incestuous nature of USC and the athletic department, which is why Haden fired him from his PA job at the basketball games. When I started working here, I actually asked Petros for advice and he said, partially tongue in cheek, "Don't criticize anyone!" He's not really welcome on campus anymore, which is a real shame, since he's a really interesting guy and comes from a family of Trojans. But he committed the one unforgivable sin at USC, which is speaking negatively about USC. For ****s sake, OJ's Heisman is still in Heritage Hall, but Petros is banned. USC is a weird place.
