What would stop VT doing similar to what Hammam did?

These owners don't exactly publicise the facts of their true intentions while still at the club. Usually not until they have left the club and you suddenly see the other side of their character.
Sam Hammam changed from loveable, fun owner to the clubs main enemy almost overnight. What would stop VT doing something similar?

It seems beyond odd that an owner has had interest in others buying the club and blankly refused to even entertain them (info from recent meetings with Dalman) but seems content on cutting club expenses in any way they can while still pumping money in.
It all seems very odd. Why would somebody like VT hold onto a club like Cardiff City on it's current inevitable (due to the above mentioned cost cutting) slide.
