I tend to think corporations have some responsibilities to consumers. EU looks great, but it’s an additional product for which Universal will charge full price. In no way, shape, or form does its construction relieve them from responsibility for the other products for which they charge full price. Slowing the addition of new attractions due to pressure from EU is a reasonable measure. Shuttering portions of a park indefinitely and running attractions without their full show to save money is not.
And yes, most guests will notice that an entire land is empty except for a (very nice) sit down restaurant. Guests can be oblivious, but they aren’t complete fools.
