The APUG membership is not a statistical outlier to be ignored simply because it's not saying what you want to hear. Rather it's a repository of 66,474 once or greater enrollees who felt strongly enough about the product category of photographic film to sign up as members. And the product preferences expressed here by them are genuine. People aren't gratuitously lying about the products they want to buy and use, if those products were made available. Why on earth would they do that?
It's not a sickness. It's the market at work.
My humble advice would be that one ignores the expressions of this cost-free market research at one's own risk.
