I haven't denied any such thing. So what you are saying is that they got themselves so deeply in the hole over EPCOT they had to get corporate sponsorships. OK, how does that change any of what I am talking about? What does that have to do with the park that opened on 10/1/82? I just don't see the nobility in that.
Basically, what it seems like you are saying is exactly what I was saying - the park that opened in 1982 had little to do with any of these esoteric ideals that are now ascribed. If the Internet had existed in 1982 people would have been screaming just as much about the place not being "Walt's Vision" - the theme park that folks are so attached to never got built to begin with, yet 35 years later people are still clinging to a park that was never built and inexplicably criticize the company for still not building it.
"Heart?" Are we really going there?
No, I just disagree with your premise because there is no empirical evidence of it. What people were drawn to in 1982 was the lavish attractions. In the past 35 years, these two things have become inexorably intertwined in the minds of certain fans. People didn't go to EPCOT because of "optimism" and especially not "heart" - it's very difficult to even use that word when discussing EPCOT as it's always been rather sterile. It never was a "warm hug" park to begin with. The things that led you to believe in that "optimism" were PR and marketing of the park.
What it seems you are talking about over these posts is a combination of naive 1960's "optimism" (The Jetsons) with the "corporate responsibility" theme created around the same time
by corporations to stave off government oversight/regulations, somehow all added up to a theme park based on what used to be the biggest trade show of all time (like EPCOT, we romanticize World's Fairs but they were just giant trade shows before mass media).
