And not just them!
No matter how one might romanticize Disney, Universal, etc., money has to be the basis for most every decision. If the boards don't demand it, the shareholders will. There's a reason for everything those companies do, and most lead back to money.
See the $1.2 billion poured in Disney California Adventure. That park has received easily $2 billion in upgrades in the eleven years that it's been open, and none of that was done only to make nostalgic visitors happy. It was done because Disney believes that in the long run, it will recoup that $2 billion and then some.
Business is business, but when you get too close and imagine it as something "personal," that's when feelings get hurt. Kings Island raises parking prices or charges for Dinosaurs Alive, and some here feel personally attacked, like a relative has stolen out of their wallet. When you become absorbed in a situation and build memories around it, it's hard to see it for what it really is. Visit micechat or any number of Disney message boards and you'll see how violently they pick apart the company and the way it runs the parks - similar to the way we pick apart Cedar Fair and Kings Island, seemingly forgetting that it has to come down to money. Pure and simple.
