Disney suffers more rule-breaking because of the vast online communities spreading word of how to abuse Disney's leniency.
However, I wouldn't say that everything that has changed has changed due to abuse. For example, Dawn's example of coffee vanishing from the hotel lobby is more likely attributable to the fact that guests were not sufficiently rewarding Disney for offering the coffee. Anytime you see anything given away for free by a business, it would be safe to assume the business is doing it because of how it fosters the tendancy for its customers to pay more for what they do pay for. When customers no longer show such loyalty, you can expect the freebie to vanish.
