Why do youtube creators seldom use 40k 60fps?

I figure its a matter of style preferences since 4k 30fps provides more of a cinematic feel that you might get in a movie, over 60 fps which might feel too "real." I'm not really sure though, what do you think the reason is? I guess it depends on the content really, maybe live action creators that deal with sports and such mostly shoot in 60fps, I wouldn't know. 4k 60fps probably has to be the most demanding to shoot for a camera and the most cumbersome in terms of storage, so costs probably play a huge factor I would think
