Obviously, there were more than four options (think outside the box, or perhaps outside the hub). I'll grant you what was done may well have been the most practical solution which didn't either carry an extravagant cost or require a major re-think of shows, parades, and fireworks, but that doesn't make it the best (or ideal) remedy.
Just because someone holds a differing opinion doesn't mean "there is something wrong" (with them or their viewpoint). As others have noted, the hub "looking better than it has in a long time" may well be equally true with "the hub looks far worse and less attractive than it once did".
This isn't the forum for armchair imagineering, but essentially you need fewer people occupying the hub (standing/sitting or passing through), at least during peak periods.
The best solution of the four listed, but not necessarily the best possible solution from all possible alternatives.
I hadn't seen a recent 'after' picture. If I'm honest, worse than I expected. If you can honestly say that the current hub looks better and is more thematically and aesthetically appropriate than the original, then you may apply the 'doom & gloom' label to my post(s).
Sure, it is greater usable space, but there are other (critical) considerations in theme park design beyond open, available space which have been compromised by this more spacious design.
