The FoN dedication ceremony was attended by Lillian Disney, and IIRC she helped dedicate it somehow. It was a direct tie back to Walt, if you will, possibly the last one (I don't count his windows at MK). Tearing it out basically took out whatever was left of EPCOT Center's soul.
I remember being at MK in mid-to-late December 1997 with my then-future wife, and we wondered why the flags were at half-mast. They were lowered because Lilly had died the day before we went down.
Tied back to Walt because his wife showed up to a one-day ceremony?
Sorry, but I truly find that laughable.
Epcot, as built, was not what Walt wanted. They very specifically ditched what Walt wanted. They had ideas: "Hey, about about a permanent World's Fair?" "Hey how about a cultural center highlighting nations of the world?" "Hey about about mashing them into one park!"
That fountain had nothing to do with Walt. I was just a fountain. A one day ceremony doesn't make it special.
They could have called it "Fountain of Bears" and we'd all be like, "I don't see the bears." They could have called it "Fountain of Toys" and we'd all be like, "I don't see the toys."
I don't see the nations despite being called "Fountain of Nations."
A name is not a theme.
It was just a nice fountain. It's not elevated to the Platonic plane of theme park perfection because Walt's wife attended a ceremony that took place there.
Where are are thematic purists critical of everything that contemporary Disney does because they fail on "theme"?
That fountain has always failed on theme.
