I think you're looking at "consumption" that is directly related to something productive. When one reads code, it goes towards writing (and all other examples you showed); that is essentially productive

However, what if I spend more time on Instagram and Twitter (consuming that won't lead to creating) over writing code. What if I spend more hours watching cat videos on Youtube over actually learning or making something?

Consumption in this context are what I'd call "empty calorie" consumption
