You're still not explaining the genesis of the idea. Why would Director of Magic Kingdom Entertainment Steve put forth a proposal NOT to replace the electrical parade out of nowhere such that he'd go out and fudge surveys to make it look like guests love it when they really don't? You don't see how tinfoil this is?
Director of Magic Kingdom Steve might have a interest in not replacing the parade even if replacing that parade might be the best thing for Disney as a whole.
What if Steve's personal compensation was based on survey scores, maybe he gets a bigger bonus by having a better score? He may be inclined to have questions asked in a certain way to get the answers that helps him get this bonus.
What if Steve's personal compensation is based on financial goals set by someone else in the company that is out of touch with the Magic Kingdom. If Steve goes and says he needs $30 million for a new nighttime parade, maybe that will cause him to fail in meeting those goals which might affect a bonus or career advancement.
What if Steve has a personal vendetta with someone at WDI that wants a new nighttime parade. Steve might go against it just to hurt someone else that he may consider a threat to his career or just out of personal spite.
While these are all made up scenarios, I don't think any of them are completely out of the realm of possibility or "tinfoil". Assuming that everyone in management in a company this size doesn't have personal goals that outweigh the good of the company as a whole is a little naïve.
