How has it damaged the program? They haven't played a game since last season.
Stewart was given a terrible extension by the previous AD that made it expensive to fire him after last season. I would imagine after this coming season he would have been moved upstairs into a gladhanding role, so as to again avoid paying his buyout.
Since with this report and investigation they could probably have established cause, I imagine the negotiations for his resignation are much more favorable to the university than they would have been when they wanted to hire Holgorsen.
WVU doesn't print money like Ohio State or Florida. I thought the arrangement was a creative way to deal with a problem. The offense was the big problem with WVU football the last two years (at least), along with generally poor player development and game day decision making, and recruiting. Those fall under the categories of offensive coordinator and head coach, respectively. It was clear WVU was going nowhere fast under Stewart, but couldn't afford to can him. I imagine WVU expected that Stewart would handle the situation more professionally and with respect for the opportunity he got at WVU that he would never have gotten anywhere else. But that didn't happen, and now he's gone, and his departure I imagine will cost the university next to nothing.
