First, I don't believe they own the building they are in in Greensboro. I do believe they have a long term lease and right much control. I may be wrong, but I think that is the case.
Second, I wasn't suggesting they have to remain at 5th & Summit - in fact, the should find a storefront downtown on 4th Street and put some studios and a sales office there (for all their stations) and keep the WS presence. It would be a huge mistake to move WSJS out of Winston-Salem.
Third, CC might like to have Nemenz back, but I don't think he wants any part of Big Radio anymore. As for driving people away, my experience with Howard was he only drove those away who didn't want to work! He has some interesting quirks, but can quite delightful to deal with. Those who ran afoul of him most often wanted to be their own boss and didn't want to do things his way! I could tell you more, but why give away the secrets to working for a demanding boss?
They had to drop WSJS because they were over the limit of market revenue allowed under anti-trust laws. At the time of the merger between CC and AM/FM, the combined billing would have been about 43% of the market. DOJ allows up to 40%. Long story short, they had to divest of about 3-million in annual billing, WSJS was the only single station that would achieve that (WMFR was a throw-away). So they sold WSJS and kept the four FMs. The would have liked nothing better than to have been able to keep SJS (not that I can speak for CC 0 but with the billing it is a no-brainer).
5 FMs does not put them over the limit - and even it it did, WSJS is an AM and the count is different, I do believe. Some of your techies might weigh in on that one.
