I have to say I disagree with this. Disney cares about its guests but its demise is a product of its own success. Almost every single issue guests complain about can be attributed to Disney Parks being too popular.
This leaves Disney with 2 options: reduce demand by raising the price (at the risk of increased volatility) or limit supply and voluntarily leave money on the table.
These aren't easy problems and Disney has demonstrated serious restraint here, in my opinion. They aren't perfect and have made boneheaded decisions (mistakes), but they do still care about their product and their reputation; much of which is guest experience. Mistakes are mistakes. They aren't intentionally trying to upset guests.
