But then again, I've never had any reason to believe I should ask about other things that may not be enforced as they are published. Should I ask the front desk if check out is really at 6pm and not what's posted on the reservation and the back of the door? Should I ask what the real price is of stuff marked with a price tag? I suppose anything is possible, but what reason would most people have to ask about any of those things?
Why is it morally wrong to ask questions? Sorry I just don't get why you find the idea offensive?
I've been at WDW many times when the check out time was questioned by nearby guests. Check out is at 11am, Magic Express is picking them up at 11:30am, they ask if they can leave their bags in the room for that extra half hour. I'm guessing you don't want to know the Disney answer.

Many hotel chains have clearly posted rules about late check out, (it has a name) most often it involves a small fee that the resort is happy to collect - especially when that room is going to be vacant. Also, plenty of folks have meds they need to stow safely - i.e. out of the heat. It's a pretty basic question to ask if you have meds - ie. what can they do to help you keep your meds at a safe temperature. So there's two good, non-offensive reasons why someone would ask about late check out.
Yes, you should ask if the price of the object is the real price. At least half the time I buy clothes, staff tell me there is a discount, coupon, or a sale is coming tomorrow. Companies near me are CONSTANTLY sending me coupons of various sorts. Between mail and email I get at least twenty offers a day. Many have 36-24hour windows.
If you aren't looking or asking, you are paying too much. But hey, if you think it's morally wrong to ask, keep paying full price.
So now I've given you several good reasons why I ask these questions and more. I just don't see how it's wrong to be informed. If you have no desire to be informed, why post on the DIS?
WDW has long been in the game of not informing every customer of every policy. Doing so would overwhelm most guests. Just telling them the basics overwhelms many folks.
Years ago, Disney used to offer e-nights. They were not widely published. I think we discovered it because there was a sign posted in front of GR on Main St. It was not very specific, just that this was where you went to get the bracelets. We had to ask CM's what it was. Turns out for $10,you got an extra three hours in MK. That was just ONE things I've learned by asking questions when I don't know an answer.
