I'm among those who understands and accepts why the attraction is changing, but I can say that my particular attachment to this attraction has to do with the fact that, to me, it represents the pinnacle of Imagineering. They managed to take a fairly standard amusement park ride to another level through a combination of storytelling, music, set-design, pacing, and thrills. The story builds and moves along so seamlessly to the drop and then the big celebration at the end. There's also no need to take you into several rooms to help explain to you what is going to happen on the ride as in so many other recent attractions; you just get on and it all unfolds before you. To me, it's just brilliant how well all the elements come together to create a whole experience on Splash perhaps more than on any other attraction. The music is also very catchy!
So, while I get why it's changing, I am nervous about the ability of WDI to recreate that experience with a new storyline. All the talk about salt mines and food co-ops only heightens my concern that the they'll fall into the trap of over-complicated backstories that need to be explained to be understood at the expense of creating a fun and entertaining as well as immersive experience.
