Employees can of course resign/quit/retire for numerous reasons. I think we do have a smart, very "engaged", passionate CEO, and like many maybe most CEOs. egos are usually big/common within those who achieve much, climb to the tops of corporations. So the fact that Nader may have had conflict with Dr Patterson or with certain Cytodyn executives, does not necessarily concern me, it is just so common. It would be less likely IMO, if an exec left Cytodyn, that it would be for some other negative reason, such as product problems.
