Anecdotally, Programmers Dislike "Reduce"

I’m so confused, how are you supposed to perform aggregation without reduce? This is like saying “I like plus and times, but I don’t like divide because it’s hard.” I mean sure, but you need it??

Yeah, but you never _need_ reduce. You can just have a boring loop.

I like boring code.

Not in Elixir. Unless you use tail recursion to simulate the loop. I love reduce and the other functions of the Enum module, so I have 165 calls to reduce in my code base (plus 338 map and 116 filter). It's the swiss army knife of functional programming and I don't see any problem with its usage.
