If there's an accusation that Moshiri is here to make money and cut and run, that doesn't really line up with another accusation that he's protecting himself from the stadium debt, by leaving Everton at risk.
If the stadium debt put Everton in trouble, that directly affects Moshiri's investment in EFC via share value and potential profits, as he owns 50% of the club, which will likely increase when (if) he exercises the share purchase option he has.
It's really not in his interest to put EFC at risk, as he'll end up out of pocket, via the £160m (excluding transfer money) he's already put into the club, in his first year.
