Yeah, I see your point but I think for most, it was and is all about what helps the program most. The perception by the majority was that Boeheim was hurting the program more than he was helping it (and I'm just talking about his final few years of course). If last year Boeheim had led the program to another sweet 16 and recruiting was strong, very few would have complained and wanted him gone. It's all about winning.
Regarding Weitsman, it was perceived by most that he was helping the program more (with his cash) than hurting it. That perception has obviously changed recently.
Bottom line... people want to win first and foremost.
