You’re wrong, they got a lot of bad publicity off that from respectable news outlets, many people who read Bloomberg came away with a downgraded view of UNC. Or maybe they read your post and favored that instead.
How many is many? The number of people who regularly read Bloomberg would probably fit in someone's living room. What respectable news sources? A few internet blogs and a handful of online reporters?
Their image is not going to be damaged unless the knowledge of the scandal is widespread across virtually all media. It's not even close to that. Even the outlets that reported the scandal published one article and then moved onto the next story. Only a few UK fans on this board keep mentioning it. I never see it mentioned anywhere else.
