I think you're plain wrong. I have never talked to anyone in my life about phones who didn't want replaceable batteries and wasn't annoyed by the throwaway culture. It's a top priority for the people I know, though by far not important enough for most of them to go for something like a Fairphone.

However, these preferences don't really matter anyway because nobody is forced to replace the battery and not buy a new phone when their phone has replaceable batteries.
