It's probably more so that there are people who care, but more people who manage budgets. I work at a Fortune 5 company and the amount of insanity it takes to get budget to do a project is unbelievable. They are simply managing costs and it's not "worth it" to fix the Yeti.
The trouble is, this kind of thinking is financially sound in the short term, but not in the long term. My opinion is everything has to be managed as a book - A large "overall" strategy. Trying to take every single incident and do ROI analysis on it will lead you down a path of doom. Not everything you do will be profitable, cost effective, or even financially logical.
However, managing the business for a quality and premium experience forces good management to spend money on things like the Yeti and other maintenance. Disney has bad management at the moment. The Yeti is also integral to the ride experience, so one could argue it is more critical than the broken actuator on Splash. It's all important, however, if you want to maintain the Disney brand over time.
