Their most popular ride? Very very debatable. Secondly, to strictly make a political statement? No. WDI/DPEP's mandate from Burbank is to infuse IP, Tiana was an appropriate IP to replace this flume attraction with.
Disney has proven that infusing IP (whether you like it or not) drives revenue. If you are so concerned as a shareholder you should be happy to know this attraction will be printing money in merch sales.
They will delete your post because it is in clear violation of the terms and services. SotS is basically an unknown IP to 95% of the General Public. I can guarantee you that up until Splash closed, you could ask 100 people exiting Splash if they knew where those characters came from and maybe 2 people would know. It is not a franchise, it is a movie that Disney locked in a vault decades ago. Again, as a shareholder you should be happy that Disney is adding modern IP that people are actually interested in to the parks.
