Depends on what you mean by "owe". I agree that they need to live up to their own rhetoric about customer service. They need to provide services suitable to their various price points. Because as someone else said- there are a lot of other places you could go with the money.
But I also agree with the person that said upthread that their target audience is not the fans. It's the families with children, and while Disney clearly wants to continue to market themselves as a multigenerational trip, they aren't ever going to stray away from that target audience. They know they'll lose families with teens to Universal. They aren't really trying to compete with Universal. I definitely think it's more that Universal is trying to compete with them. Maybe Universal will pull ahead and Disney will start to spiral downward. But I just don't think that has happened yet. People have said they can go other places. Well, Disney isn't stopping you and most people DO go other places. People have said Disney has to live up to its own media image. C'mon. Who here really believes Disney parks are a Utopia where nothing bad can happen and you'll always be happy? They're amusement parks.
And as someone who likes Disney but is not really a believer in pixie dust- I think that some Disney fanatics are their own worst enemies. I see some of craziest, most entitled stuff on these forums. I did the math for a AP. I'd have to go on at least 2 1 week trips to pay that puppy off. 14 calendar days a year. If you go that much, of course you're going to feel like they aren't updating fast enough. Of course you're going to have some days where you encounter less than magical CMs. Of course you're going to get tired of the rides and the food. And as much power as APHs have, it's limited. Disney is well aware that we returnees spend less money. They have a harder time upselling us. In California, especially, I'm fairly sure the most money they get out of the locals is the AP. The APs are their bread and butter- it's necessary to keep them in the mood to come back- but the tourists are their cash cow.
Anyway. We are owed what we actually pay for. A clean room, an edible dinner, a day at the park, recompense if something goes wrong and Disney is at fault. But we aren't owed ridiculous upgrades or champagne service on a value resort budget or "pixie" dust or towel animals or short lines or the right to break the rules. (For every person that has a valid complaint, there are 10 people at WDW today arguing with the bus driver over whether they have to take their kid out of the stroller and fold it in order to board the bus. And people seriously wonder why the buses can take a little longer!)
