They're not entirely wrong.
The company seems content to rake in the $$ from WDW while skimping on maintenance, show quality, and so on there.
There's also been a decided tendency to erase Florida-specific design decisions in favor of replications of DLR design decisions whether or not it makes any sense within the context of the FL environment:

And of course, the 50th. For its 50th, Disneyland received lavish refurbishments, a new parade, and Remember. WDW got statues, some food and merch, and a paint-by-numbers fireworks show that has nothing to do with the park or resort. Heck, they could've just stolen Celebrate! Tokyo Disneyland and just swapped out the ride audio, but no, they chose generic-R-us Disney fireworks show # 33 instead. This is all the more striking to me at the moment because I just got back from an evening at Kings Island, which is
also celebrating its 50th right now and has put up historical timelines and pictures, refurbished a lot of attractions and areas, and put in a lot of entertainment, including a stage show modeled after a defunct dark ride and a fireworks show that pays tribute to park history with modest projection mapping and drones! Of course the scale is much smaller, but it's clear that people at Kings Island care about their park's history, and there's no evidence that the same is true of WDW, or at least among anyone in a position of significant power.
It's VERY clear they have no idea what to do with Epcot and have no real respect for what that park represented.
So while it's easy to look at all of the additions they've gotten over the past decade and conclude that the WDW fanbois are wrong, there's plenty of evidence that the resort still is stuck in Disneyland's shadow, the only one in the world for which that's really true. It's easy to conclude there's no vision or appreciation for what WDW was, is, and could be besides just the company's ATM.
