This happened at an old employer of mine. We started to go down the FP road, veering off the standard OOP of the day. About 25% of the people picked it up immediately. About 50% got it well enough. And 25% just thought it was arcane wizardry.

Between that latter group and the bottom portion of the middle it sparked a big culture war. Eventually leading to leadership declaring that FP was arcane wizardry, and should be eradicated.
