Why is it a stretch? Only a tiny itsy bitty minority even know what FP is (a little more these days because of some JS frameworks and reactive programming, but still). Then among the people who do know about it, an even smaller fraction learnt about it first, or in the same depth. Among those who did, very few learnt it in a practical way (Learning ML in college is unlikely to get someone to use FP to build production software, especially before ReasonML was a thing). With all that, is it a stretch to think people don't use FP because they don't know about it? No, I don't think so. It could be 100% objectively superior in every way and people still wouldn't use it in those circumstances. And its' far from being "obviously" better.
