It's the opposite, actually. "Experts" are pushing for higher framerates, but "average viewers" complain that something feels wrong, home-video-y, and just plain weird on high-FPS movies. They can't put their finger on it, they certainly won't mention the framerate, but they tend not to like it.
Because ordinary people don't spend the time to appreciate it, it just look too different for them. Exactly how color movies looked too different at the time.
Not true. This pattern is the same you saw with iPhone "nobody would use that" or CDs or ipads, or video games or ... there are always people who are against progress.
