It's not really the salaries, but the rabid defense of the tens of millions of dollars Diwan dumps into his private company.
It has been repeatedly asserted that this arrangement is fantastic, because it prevents NNVC investors from a "hostile takeover", of all absurd things.
The bottom line is, Diwan's money-skimming arrangement with his private company which he owns, with him and his wife being the only two officers of NNVC making all its decisions, is all public information.
Anyone who invests in NNVC in view of this information either 1) supports this arrangement, or at least doesn't see any problem with it, or 2) has not done the minimal due diligence to understand what they're invested in.
