Some people prefer FP. Some prefer OOP. Some need just a sprinkling of interactivity. Some need to build complex UIs. Some need to run on underpowered devices while others don’t. Some dislike too much abstraction. Some prefer it.

In short, we have a plethora of frameworks for the same reason we have a plethora of languages, sodas, beers, coffees, tools, products, novels, etc. Humans are messy.
