It can bother you all day long, but it is what it is, and to fret that they won’t pony up money to create a “new version of old Epcot” is only going to lead to frustration and disappointment.
Except it's not about the money, it's about the how they're spending it. The money they're currently ponying up is more than enough to put things back on the right track, but it's being spent in a way that both moves the park further away from what made it unique and successful, and will also leave the park feeling incomplete when the work is done.
Take for example The Seas with Nemo and Friends, which opened in 2007. It's based on the popular and successful 2003 film, which had a popular and successful sequel in 2016. By all accounts, it fits the "timeless, relevant, family, Disney" direction that the current renovations are following. And yet, it hasn't been a major draw to the park since shortly after it opened 14 years ago. Is this really an improvement over a more classical Epcot approach? At best, most guests seem to use it as a way to burn their third FP+ reservation, as a forgettable diversion on their way to do something else. A park filled with attractions like this would fail to draw guests away from the other 3 parks, because it adds nothing new to your multi-day vacation; it's just more of the same, executed at a poor-to-middling level. Why bother going to Epcot when Magic Kingdom does the same thing, but better?
Instead of spending the money to spruce up the existing attractions in the park and turn them into worthwhile experiences, they're largely being ignored. Meanwhile, they're spending enormous sums of money to build new attractions that likely won't resonate with guests 15 years from now, and the existing attractions will be even more dated and forlorn by then. Instead of adapting the existing multi-use infrastructure for a new purpose, they're demolishing it and building expensive replacements that aren't as flexible. Instead of giving the whole park a meaningful update, they're dumping huge piles of cash in a couple spots and ignoring the rest.
As with almost all of Epcot's history, it's not the money that's the problem, it's how it is spent. Even after riding the notoriously "cheap"-seeming Imagination 2.0 redo, Michael Eisner furiously wanted to know where all the money had gone, because its budget was far greater than the result would imply.
By all accounts, they're spending enough money that they could make a really positive difference for the park; however, the way that money is being spent leaves very little to show for it.
