Tell that to Disneyland people. Disneyland locals make their voice heard. They make their complaints to guest relations/the company known, they back it up with their actions, and many times TDA actually listens. Just a few examples I can think of off the top of my head...when they wanted to axe Aladdin back in the 2008/9ish timeline to bring in a Toy Story musical. Backlash caused TDA to change their mind and keep Aladdin around until it closed in 2016. I also remember an issue with BBB no longer having Photopass photographers to take pictures during the experience (can't remember if this was DLR, WDW, or both). People complained, asked for refunds, etc - and Disney reversed course. I also would not be surprised if RDCT has now returned because they were getting backlash about the "lesser" Fantasy in the Sky show that replaced DLF.
It isn't like the people making these complaints aren't having fun while in the park. They are. But they have issues with certain things as well, and they make them known. Will Disney listen and back track every time? No, of course not. No one's suggesting that. But just accepting whatever it is they are choosing to do (in this case, replace a nighttime spectacle with another showing of an afternoon dance party), will never result in changes. Disney won't change anything if they don't have a reason to think it's a problem...and they have no reason to think there's an issue if no one ever says anything to them.
