I dont think it's that people aren't enjoying it. My last trip was early 2020 and we had a great time, but some things irked us, like the parks closing early so that they could then be reopened for people willing to shell out additional money for the "after dark" tickets or whatever it's called. Much shorter park hours, higher prices, and the general feeling that you're getting less than what you're used to and paying more. Since then they've gotten rid of DME and added this elitist Genie thing. It all adds up to feeling exploited. Combine that with the strong emotions many of us associate with Disney, and you have a recipe for people reaching their last straw.
