I'm sure this has been said but the reason many people dislike Duffy is when you are basically told "YOU WILL LIKE THIS." Figment is the one true "mascot" of Epcot. Figment if anybody should have had the themed costumes around World Showcase. But some ignorant Disney high up exec came back from Japan and thought "Hmm.. Those Japanese love Duffy. They spend a ton on it. Japan is much smaller than the United States. Can you imagine how much we'll sell in the U.S?"
Duffy was popular in Japan for a few reasons but I would say partly because it was created for them. And that's cool.
But to me, I don't like something forced on me just because some MBAer thinks it'll sell a ton of merchandise. You can't force something like that on guests. Phenomenons are usually natural.
Now, I don't fault anyone who liked the bear (maybe I do haha), but that's why he bugs so many. Now give me a Figment with lederhosen !
