Don't quote me on this, but isn't 24 fps the minimum required for the human brain to interpret motion, and not just a series of still images? Maybe they are just following the law of minimum efford...
Yes. 24 fps was the standard for technical reasons for many years yet people, critics and creators are still beating the drums sayong it looks better than higher rates and should be kept as the stnadard. Like those fools who used to say vinal is better for it's flaws. It seems to be all nostalgia based and no reality to it at all. I think it may just e social engineering so the elite don't have to go and replace all their infrastructure and tech and the streaming service don't need to fouble bandwith. Or maybe it's just foolish people being foolish or like you said, lazy and doing the bare minimum.
