It's rare that people bother to learn new things on their own whereas it's common for them to punish people that make it trivially more difficult for them to counterfactually do so, even though they wouldn't even have been primed to want to do so if that person hadn't brought up the subject. That's the thing I'm complaining about. (bla bla marginal cost something bla opportunity costs b;'dja. disclaimer disclaimer disclaimer.)
