I agree and I think rules are pointless. Everything is a tool and you pick the right tool for the job and that requires context and thinking. However, having built systems in OO and then in functional, I've come to realize that the OO tools always have a surface of familiarity (`cat.meow()` vs `meow(cat)`) but are highly coupled (inflexible) while the latter, functional composition is not. And if there's any objective measure to complexity it's a measure of degrees of coupling. And OO distinctly loses to functional there.
