"I don't like this style of FP coding" ok: if you run the group and own the codebase you can enforce that. So good refactoring is style guide enforcement.

I think I over-read his dislike of FP. really the complaint is "why did you introduce a new dependency" which I am totally fine with, as a complaint. Thats not cool.

Many of his examples kind-of bury the lede. If he had tried to write an abstract up front, I think "dont code FP" wouldn't have been in it. "use the methods in the language like .filter and .map" might be.
