In my experience, I have seen much less of the OOP-only group, especially in recent years. The general feel I have seen when communicating with other developers about this is that OOP is a tool and it's probably not the best one, but they are comfortable with it and it's problems.
In general it feels like the overall feeling to FP is either
"I don't have time to learn a new paradigm when my current one is working good enough to make the company money"
or
"I love using FP ideas in my code when it makes sense"
I really feel like this is the ideal state for Software Development, as either side "winning" will only hurt the robustness of the environment.
Oh, sure! I didn't mean to suggest that there were as many as the only-pure-FP crowd, though I can see how my phrasing may have suggested as much. I just meant to bring up that there are people like that, who refuse to (consciously) adopt any amount of FP in their development. I have interacted with some myself. Most of them make arguments about, like, "People think in terms of state so FP is inherently a bad user experience" or something to that effect.
