Aside from being just plain inappropriate and overwrought, Forbin's analogy and the other fannish indignation has the situation just plain backward. Here's a similarly ridiculously exaggerated analogy that has the virtue nonetheless of being more accurate:
Mom is dying of a degenerative illness. She goes off to a clinic and returns, in better health than she's seen in twenty years and virtually cured. But as she comes off the plane some of the kids shout "Mom has never worn her hair that way! It's the wrong color! The clinic beauticians are incompetent! Ruined forever! Aggggh!"
I live about five miles from the museum, BTW. I've seen the model hundreds of times, in every version of maintenance/restoration and every display location.
