It is not the horror that Ichan wants to get a return. It is the horror that he could give crap about the company. If getting his money means throwing the company under the bus, he is going to be for throwing the company under the bus.
It is not too significantly different that a Mafia protection racket. "You need to funnel money into my pockets or your business life might happen to run into drama/trouble". If he was actually contributing something in return, but he really isn't. He should get more money largely because he has a big pile of money. Yeah horror is in there.
I get the sentiment held by many that Icahn is something of a corporate raider. I just think that many here are overestimating the influence and power he can have as a 0.5% stakeholder in the most valuable company in the world that has a more than healthy balance sheet.
