As a recent convert to haiku writing, I've seen a lot of that in English-language non-literary spaces. People get a 10-minute class on 'now write a 5-7-5 poem' when they're 11, and they come away thinking that it's more an arithmetic lesson than an artform in itself. Even people I really like, who are generally thoughtful and smart, have responded to me sharing some haiku with 'dude, can't you count, those aren't 5-7-5' because that's often the only criterion they've heard of.
