Functional purists are the only one's who hate it. OOP by its very nature encourages developers to make bold abstractions prematurely (where prematurely is interchangeable with unnecessarily) and subjectively. Mean while the procedural programmer (Golang) has already finished the segment of the program having written one big function. If a piece of that big function is needed elsewhere she factors it out. Most of her program are simple loops and conditionals. Programs are easy. Programs are easy, why complicate something that is easy.

The machine should also guide the programmer as much as possible. I wish Golang had refinement types like Liquid Haskell or ATS. Some simple static analysis to cut down on crufty slow runtime test suites.
